Context7 gives your agent the docs. Context8 gives it what the docs don't cover.

Every time a coding agent solves an uncommon error, the solution vanishes after the session. Context8 stores those solutions in a vector database so any agent — yours or your team's — can find them next time.

Agent hits error → searches Context8 → finds a past solution → applies it
                                            ↓
                     Agent solves new error → logs it to Context8 → future agents benefit

Prerequisites

RequirementWhy
Python 3.10+Runs the Context8 CLI and MCP server. SQLite ships with stdlib; sqlite-vec and FTS5 do the rest.

That's it — no Docker, no daemon, no separate database to install.

Quick Start

# 1. Install Context8
pip install context8

# 2. Initialize the local DB and seed with 23 curated problem-solution pairs
context8 init --seed

# 3. Wire up your coding agent (pick one)
context8 add claude-code   # Claude Code
context8 add cursor        # Cursor
context8 add windsurf      # Windsurf

# 4. Verify everything works
context8 doctor

Restart your agent. It now has these MCP tools: context8_search, context8_log, context8_rate, context8_search_solutions, context8_stats.

The DB lives at ~/.context8/context8.db — a single SQLite file with three named vector spaces (problem, solution, code_context) backed by sqlite-vec and an FTS5 BM25 index for keyword search.

Optional: Actian VectorAI DB backend

The original hackathon submission used Actian VectorAI DB over gRPC. That stack is still supported as an optional backend. The Actian SDK isn't on PyPI, so install the GitHub wheel directly alongside context8:

pip install context8 \
  "actian-vectorai @ https://github.com/hackmamba-io/actian-vectorAI-db-beta/raw/main/actian_vectorai-0.1.0b2-py3-none-any.whl"

docker compose up -d                       # starts the Actian container
CONTEXT8_BACKEND=actian context8 init --seed
CONTEXT8_BACKEND=actian context8 doctor

Set CONTEXT8_BACKEND=actian (or leave unset for the default sqlite). The same MCP tools, search semantics, and CLI commands work across both backends.

Why two install lines? PyPI doesn't allow published packages to declare URL-pinned dependencies, so we can't ship an [actian] extra that pulls the wheel automatically. Once the SDK lands on PyPI, this collapses to a single pip install context8[actian].


Context8 vs Context7 vs Skills

Coding agents have multiple ways to get help. Here's where each one fits and where it falls short:

The Context Layers

LayerSourceWhat It CoversLimits
Context 1–6Codebase, conversation, memoryYour current project's files and historyOnly knows your code
Context7Official documentation (Upstash)API references, common usage patterns, getting-started guidesOnly covers documented knowledge
Skills / CLAUDE.mdHand-written rulesProject conventions, tool-specific patterns, coding styleManual maintenance, doesn't learn
Context8Agent problem-solving history (local SQLite + sqlite-vec)Uncommon errors, workarounds, integration bugs, agent-discovered fixesNeeds seeding and accumulation

When Each One Helps (and When It Doesn't)

ScenarioContext7 (Docs)Skills / RulesContext8 (Memory)
"How do I use the useQuery hook?"Best fit — it's in the React Query docsPartial — if someone wrote a skill for itOverkill — docs cover this
"What's our team's folder naming convention?"Won't help — not in public docsBest fit — written in CLAUDE.mdWon't help — not a problem/solution
ERESOLVE unable to resolve dependency tree after upgrading npmPartial — npm docs mention peer deps vaguelyWon't help — too specificBest fit — exact error with proven fix
Hydration mismatch in Next.js 15 + React 19 RCOutdated — docs haven't caught upWon't helpBest fit — another agent hit this last week
torch.cuda.OutOfMemoryError during fine-tuning even with batch_size=1Partial — PyTorch docs cover CUDA basicsWon't helpBest fit — solution with 4 ranked fix strategies
docker compose volume empty on Windows WSL2Won't help — Docker docs assume LinuxMaybe — if someone added a WSL tipBest fit — exact OS-specific workaround

The Key Difference

Context7:  "Here's what the library author wrote in the docs"
Skills:    "Here's what a human wrote as a rule for this project"
Context8:  "Here's what an agent actually did to fix this exact problem last Tuesday"

Context7 is a librarian — it finds the official answer. Skills are a style guide — they enforce conventions. Context8 is a colleague — it remembers what worked in practice.

They're complementary. Use all three:

Agent encounters error
  ├── Check Skills/CLAUDE.md → "Do we have a rule for this?" (instant, project-specific)
  ├── Search Context7 → "What do the docs say?" (official, broad coverage)
  └── Search Context8 → "Has any agent solved this before?" (practical, battle-tested)

How It Works

Context8 is an MCP server backed by SQLite + sqlite-vec by default (Actian VectorAI DB optional). When your agent encounters an error:

  1. Search — Agent calls context8_search("TypeError Cannot read properties of undefined map React Suspense")
  2. Match — Context8 runs hybrid search: dense semantic vectors find meaning-similar problems, sparse keyword vectors catch exact error tokens, metadata filters narrow by language/framework
  3. Return — Agent gets ranked solutions with code diffs, confidence scores, and context
  4. Learn — After solving a new problem, the agent calls context8_log(problem=..., solution=...) to store it

Three Search Strategies, Fused Together

StrategyVector SpaceWhat It CatchesExample
Dense searchproblem (384d, MiniLM)Semantic meaning"undefined array access" matches "null reference on collection"
Dense searchcode_context (384d default, 768d with CONTEXT8_USE_CODE_MODEL=1 for CodeBERT)Code patternsdata?.items ?? [] matches optional chaining null safety
Sparse searchFTS5 BM25 (SQLite) or sparse keyword vectors (Actian)Exact tokensModuleNotFoundError matches ModuleNotFoundError exactly

Results are fused with Reciprocal Rank Fusion (RRF) and filtered by language, framework, and more. The QueryAnalyzer auto-detects query type and adjusts fusion weights:

Query TypeDense WeightCode WeightSparse Weight
Error message (TypeError: ...)0.400.150.45
Error + code context0.350.300.35
Code snippet only0.250.550.20
Natural language question0.600.150.25

MCP Tools

Once connected, your agent has access to:

context8_search

Search for past solutions to a problem.

Input:  query (required), code_context, language, framework, limit
Output: Ranked solutions with problem, fix, code diff, confidence, tags

context8_log

Log a resolved problem for future agents.

Input:  problem (required), solution (required), error_type, code_snippet,
        code_diff, stack_trace, language, framework, libraries, tags, confidence
Output: Confirmation + record ID (or duplicate detection)

context8_stats

Knowledge base health check.

Input:  (none)
Output: Record count, collection status, vector spaces, endpoint

CLI Reference

context8 stats                          # Show knowledge base statistics
context8 doctor                         # Full health check (verifies named/sparse/hybrid/filter)
context8 search "query"                 # Search from the command line, with attribution
context8 search "query" -l python       # Search with language filter
context8 bench                          # Run retrieval benchmark, print Recall@K table
context8 demo                           # Scripted live demo of all advanced features
context8 import-github vercel/next.js   # Pull resolved issues from a GitHub repo
context8 serve                          # Start MCP server (agents call this automatically)

What's in the box

Five capabilities that turn the basic "MCP + vector DB" pattern into a production-grade framework:

1. Real-world ingestion at scale

Beyond the 24-record curated seed, Context8 ships an importer that pulls resolved issues straight from GitHub:

context8 import-github vercel/next.js --label bug --max-issues 50
context8 import-github fastapi/fastapi --max-issues 30
context8 import-github huggingface/transformers --label bug --max-issues 30

The importer scans the closing comments for resolution markers (fixed in, the fix is, workaround: …), extracts language/framework/error-type signals from labels and repo names, and stores everything as Context8 records. One command, hundreds of real production fixes in your DB.

2. Agent feedback loop (context8_rate)

Context8 is bidirectional. After an agent applies a retrieved fix, it calls context8_rate(record_id, worked=True). The record's worked_count/applied_count updates and feeds straight into the ranker — solutions that consistently work float to the top, ones that fail sink. This is the closed feedback loop that turns a static knowledge base into a self-improving one.

3. Per-strategy attribution

Every search result tells you exactly which Actian strategy surfaced it and at what rank:

Result 1 — score: 0.812 (raw: 0.945) — confidence: 95%
  via: keywords@1 (0.95) + problem@2 (0.78) + code_context@4 (0.61)
  boosts: confidence 1.00  recency 0.94  worked_ratio 0.92
  feedback: 7/8 worked (88%)

You can see the dense vector contributed less than the sparse keyword match, the recency factor barely penalized this record, and 8 prior agents have used this fix with 7 successes. The MCP tool returns the same attribution so agents can reason about result quality.

4. Quality ranker (search/ranking.py)

Final score = retrieval × confidence_factor × recency_factor × worked_ratio_factor. Each multiplier has a configurable floor (so a 0-confidence record loses at most 30%, never gets zeroed out), and feedback only kicks in once a record has been applied at least 3 times — preventing single bad ratings from sinking new solutions.

5. Evaluation as a first-class artifact

context8 bench ablates one Actian feature at a time over 27 ground-truth queries and prints a side-by-side table with green deltas. context8 demo runs four scripted scenarios (named vectors / hybrid fusion / filtered search / quality ranker) — designed as the script for a submission video.

Capabilities (and how each backend delivers them)

The same three capabilities work across both backends — only the underlying mechanism differs.

CapabilitySQLite + sqlite-vec (default)Actian VectorAI DB (optional)
Hybrid FusionDense vec0 KNN + FTS5 BM25, fused with RRF in pure PythonDense + sparse vectors, fused with av.reciprocal_rank_fusion
Filtered SearchSQL WHERE over indexed columns + JSON1 json_each for tag arraysFilterBuilder over the payload
Named Vectors3 vec0 virtual tables: vec_problem, vec_solution, vec_code_context3 named vector spaces in one collection

Prove it: context8 bench

The benchmark ablates one feature at a time over a 27-query ground-truth set and prints a side-by-side comparison:

context8 init --seed
context8 bench

The output table shows Recall@1, Recall@3, Recall@5, MRR, and p50 latency for four configurations — dense only → + named vectors → + hybrid fusion → + filtered search — with green deltas vs the baseline. Each row turns on one more retrieval feature. The deltas are the proof.

Run it under either backend:

context8 bench                          # SQLite (default)
CONTEXT8_BACKEND=actian context8 bench  # Actian

See it: context8 demo

A live, scripted three-scenario walkthrough designed as the script for a submission video:

context8 demo
  1. Named vectors — the same record retrieved three ways: by error text, by code pattern, by solution approach. One record, three independent vector spaces.
  2. Hybrid fusion — ERESOLVE unable to resolve dependency tree on dense-only vs. dense + sparse RRF, side by side.
  3. Filtered search — same query, language filter flipped between python and javascript, results swap server-side via FilterBuilder.

Verify it: context8 doctor

The health check asserts the three features are actually live — no silent degradation:

sqlite-vec                ✓  0.1.9
Backend connectivity      ✓  SQLite + sqlite-vec @ ~/.context8/context8.db
Schema                    ✓  records table present (23 rows)
Named vectors (3)         ✓  3 found: code_context, problem, solution
Sparse (FTS5)             ✓  fts_records virtual table present
Hybrid fusion ready       ✓  dense + sparse + RRF available
WAL mode                  ✓  journal_mode=wal
Filtered scroll           ✓  returned N record(s)

Releasing

# Bump version in pyproject.toml and src/context8/__init__.py, add a
# changelog entry, then:
git tag v1.0.0
git push --tags
# CI runs → PyPI publishes → GitHub Release created automatically

Post-v1, follow semver: bump the patch for fixes, the minor for additive features (e.g. a new backend), and the major only for breaking changes to the surface listed in the v1.0.0 changelog entry.


Changelog

v1.0.0 — SQLite-first, public API stable

The version jump from 0.x to 1.0 marks two things: (1) the default install is finally a one-command pip install context8 with no non-PyPI wheels, and (2) the public surface — MCP tools, CLI command names, env-var conventions, and the StorageBackend Protocol — is now committed to under semver. Future backend additions (e.g. Postgres + pgvector for a hosted version) will be additive third Protocol implementations, not breaking changes.

Public API surface guaranteed under semver:

  • MCP tools: context8_search, context8_log, context8_rate, context8_search_solutions, context8_stats.
  • CLI commands: init, start, stop, doctor, stats, search, browse, add, remove, bench, demo, serve, export, import, import-github, mine.
  • Env vars: CONTEXT8_BACKEND, CONTEXT8_DB_PATH, CONTEXT8_DB_HOST, CONTEXT8_DB_PORT, CONTEXT8_USE_CODE_MODEL, CONTEXT8_TEXT_MODEL, CONTEXT8_CODE_MODEL, CONTEXT8_RECENCY_HALF_LIFE_DAYS.
  • Backend Protocol: StorageBackend and the SearchFilter / ScoredHit dataclasses in context8.storage.
  • JSON export format (format: "context8-export", version: 1) — backend-agnostic, used for cross-backend migration.

What changed in this release (full rollup from 0.4.0):

  • Pluggable storage backends. SQLite + sqlite-vec + FTS5 is the new default — no Docker, no daemon, single-file DB at ~/.context8/context8.db.
  • Backward-compatible Actian backend. Install the SDK wheel from GitHub alongside context8 and set CONTEXT8_BACKEND=actian to keep using the original hackathon stack. (PyPI doesn't allow URL-pinned extras, so the install is two lines instead of one.)
  • Search engine refactor. search/engine.py no longer imports a vendor SDK; it talks to a StorageBackend Protocol. RRF moved to search/fusion.py as pure Python.
  • Backend-aware CLI. start/stop print "no daemon needed" under SQLite; init runs schema migrations; doctor checks file integrity, WAL mode, vec0 + FTS5 modules.
  • Concurrency. WAL mode + 5s busy timeout for parallel MCP reads while ingest writes.
  • vec0 dim guard. Flipping CONTEXT8_USE_CODE_MODEL after init fails loudly with a --force hint instead of silently corrupting the DB.
  • New tests. tests/test_storage_sqlite.py (18 unit tests), tests/test_e2e_sqlite.py (full e2e on SQLite), tests/test_search_filter.py (filter translation). 127 tests pass on a fresh checkout, 15 Actian-only tests skip cleanly without CONTEXT8_BACKEND=actian.
  • Fixed pre-existing test bug. FeedbackService(storage, embeddings) arity mismatch in test_e2e.py:281,300.

Migration from 0.4.x:

# If you had data in the Actian backend:
CONTEXT8_BACKEND=actian context8 export -o backup.json
pip install -U context8                    # pulls v1.0.0
context8 init                              # creates fresh SQLite DB
context8 import backup.json                # re-embeds and imports

If you want to keep using Actian: pip install -U context8 "actian-vectorai @ https://github.com/hackmamba-io/actian-vectorAI-db-beta/raw/main/actian_vectorai-0.1.0b2-py3-none-any.whl" and set CONTEXT8_BACKEND=actian. No other changes required.

v0.4.0

  • Container runtime: Docker + Podman auto-detection with cached probing
  • Self-bootstrapping serve: context8 serve now starts DB, inits collection, and caches models before the MCP loop — works on a cold machine with zero prior setup
  • --no-bootstrap flag: skip auto-bootstrap if you manage infra manually
  • Hybrid search restored: sparse vector detection now reads collection info on every startup instead of defaulting to False
  • Sparse search fix: passes SparseVector object with using="keywords" (was rejected by server)
  • Async MCP fix: tool calls wrapped in asyncio.to_thread — no more event loop blocking
  • Browse resource leak fix: gRPC client always closed on no-results path
  • Embedding cache fix: hash full text, not just first 500 chars
  • Configurable dims: TEXT_EMBED_DIM / CODE_EMBED_DIM flow through everywhere
  • CodeBERT env var: CONTEXT8_USE_CODE_MODEL=1 enables 768d code embeddings
  • Browse + ecosystem MCP tools: metadata filtering and stack-based discovery for skill writing
  • Auto-capture + auto-suggest hooks: Claude Code hooks for zero-effort logging and retrieval
  • Session mining: context8 mine ~/.claude/sessions/
  • Export/import: context8 export -o backup.json / context8 import backup.json
  • Solution versioning: same problem, different fix stored as variants
  • Batch ingest: ~20x faster for GitHub imports and seeding
  • Claude Code plugin install: context8 add claude writes to plugin directory, not settings.json

v0.3.0

  • Auto-start Docker, pre-download models, one-stop context8 init
  • Docker compose generated in ~/.context8/ for pip-installed users
  • Agent config for 6 agents: Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Gemini

v0.2.0

  • Framework restructure into subpackages
  • GitHub Issues importer, feedback loop, quality ranker, per-strategy attribution
  • Benchmark suite with Recall@K ablation
  • 79 unit tests

v0.1.0

  • Initial release: MCP server, hybrid search, 24 seed records, CLI
