digikala-mcp

An MCP server for Digikala product discovery, product research, offer comparison, and bounded cart operations. Consumer applications own the conversation, product selection, user interface, and approval of cart changes.

Responsibilities

Location	Responsibility
`src/server.py`	FastMCP factory, lifespan and tool registration; served over stdio.
`src/tools/`	Input/output contracts, tool descriptions, annotations and safe MCP errors.
`src/tools/dependencies.py`	Bridge FastMCP dependencies to Dishka scopes; injected services are absent from public input schemas.
`src/app/`	Catalog/research orchestration, comparisons, account sessions, cart planning, execution and reconciliation.
`src/infra/http/`	Fixed-origin HTTP requests, authentication, response normalization and market gateways.
`src/infra/cache/`	In-memory hash-map cache and shared tasks for identical public requests.
`src/infra/db/connection.py`	Lazy PostgreSQL engine, bounded pool and SQLModel session factory.
`src/infra/db/repositories/`	Queries and flushed writes on an injected session.
`src/infra/db/errors.py`, `exceptions.py`	Driver-error sanitization and independent persistence errors.
`src/models/schemas/`	Pydantic tool and application contracts.
`src/models/db/`	SQLModel table definitions, JSONB journal and database constraints.
`src/models/cache/`	Internal cache-entry models.
`src/providers/`	Separate HTTP, cache, gateway, database, catalog, cart and account providers, plus explicit overrides.
`src/bootstrap.py`	Compose the provider graph.
`src/config/`	Host-owned database connection and cart limits.
`migrations/`	Versioned Alembic schema changes, applied separately from request handling.

Dependency and session lifetime

The server owns one Dishka application container. HTTP clients, cache, database pool, application services and in-memory account tokens live at application scope. Each tool invocation gets a request scope. Cart services also receive an injected JournalFactory that opens a separate, short Dishka scope for each database phase.

CartJournal receives an AsyncSession; it only queries and flushes. The database provider commits on successful phase exit, rolls back failures or cancellation, and closes the session through Dishka. Concurrent phases use separate sessions. There is no custom Unit of Work or transaction-manager class, and no database session is held across storefront HTTP calls. The cache is finalized before its HTTP client closes.

Observations and cache

Public observations are cached for 60 seconds after successful completion, with up to 256 entries per process. Keys include relevant product/category IDs, query, page, sort and location. Identical concurrent reads share one task. Cache hits return independent copies and retain the original observation time; errors are not cached. Account reads, authentication, cart writes and purchase-time revalidation bypass this cache.

All monetary values are integer Iranian rials: 10 IRR = 1 toman. Missing prices, availability and shipping remain unknown. Product titles, reviews and questions are upstream text. Comparisons preserve exact offer IDs and observed attribute differences; they do not infer equivalent products or guarantee the cheapest delivered total.

Cart and account flow

A cart change follows prepare → host approval → execute → read back. Preparation creates a five-minute plan. Execution commits a journal claim before any remote write, then persists the observed result in another database phase. PostgreSQL conditional updates check ID, account, state and revision; a partial unique index permits one executing/uncertain operation per account. No application mutex or advisory lock is used.

Retries reuse the plan/request ID and never blindly repeat a mutation. Reconciliation can inspect uncertain outcomes; an executing record is not automatically taken over. Limits apply to merchandise amount and total units, excluding unknown shipping costs. The host owns approval; possession of a plan ID is not evidence of human approval.

Desktop tools use an OS-keyring account. Trusted backend account tools use isolated, process-local tokens with a 15-minute lifetime and cookies kept in memory. Passwords, cookies and tokens are not persisted in the cart journal. Payment, order placement, address selection and OTP handling are outside the tool boundary.

Tools and recorded responses

The server registers 40 tools. The examples below were captured through the actual MCP server on 2026-09-28 (UTC). Public catalog examples use live Digikala responses; price history returned the recorded rate_limited error. These are dated observations, not current price or inventory promises.

Account/cart examples use a separate process with no database connection, a disabled OS-keyring backend, and an invalid account token. They show actual validation and configuration/authentication responses, not successful live cart mutations. No real account was accessed or cart changed for these examples. The amount/unit limits shown are the capture process's settings. Zero IDs and the invalid token are deliberate test inputs, not reusable plan IDs, account credentials or verified purchase selections.

Success JSON shows structuredContent excerpts. Error JSON shows MCP isError and text content. Fields and array items may be omitted for readability; displayed values are copied from the captured responses. Each request is the tool's arguments object, without the surrounding MCP JSON-RPC envelope.

Discovery

Tool	What it does
`list_markets`	List implemented markets and capability verification status. This is metadata, not a live health check.
`get_trend_snapshot`	Read the homepage best-selling listing in upstream order, with an observation time. Sales periods and historical growth are unknown.
`list_categories`	Find native category IDs by text, parent, or root status; paginate the category tree locally.
`search_products`	Search or browse one native result page per selected market; isolate errors per market.
`get_product`	Read a product, specifications, media, rating, and observed seller offers.
`list_offers`	List offers from the product-detail response, optionally restricted to one exact variant. Coverage is limited to that response.
`autocomplete`	Read search suggestions and any category IDs supplied with them.

Inputs: None.

Desktop cart

Tool	What it does
`get_cart_limits`	Read host-configured merchandise amount and total-unit limits. Null limits disable increases.
`read_cart`	Read items, exact offers, quantities, merchandise total and known shipping for the desktop keyring account.
`prepare_cart_change`	Read and validate a proposed change, enforce limits, and persist a five-minute plan without changing the remote cart.
`add_to_cart`	POST one unit of the exact offer in an approved add plan; revalidate and read back the result.
`update_cart_item`	PATCH the final quantity from an approved update plan. Increases revalidate price, stock and limits.
`remove_from_cart`	DELETE the exact cart item identified by an approved remove plan.
`get_cart_operation`	Inspect a persisted plan or replacement and its current state for the connected account.
`reconcile_cart_operation`	Read back an uncertain operation and update its journal without resending a mutation. Executing operations remain blocked.

Inputs: None.

Token-scoped accounts

Tool	What it does
`login_account`	Perform password login for a trusted backend. Return a process-local token, expiry, or fixed failure/challenge outcome.

`update_account_cart_item`	PATCH the final quantity using an approved update plan belonging to the token account.
`remove_from_account_cart`	DELETE an item using an approved remove plan belonging to the token account.
`replace_account_cart`	Validate 1–3 exact selections, remove current items, and add one unit of each selection. Partial or uncertain outcomes block retries from resending writes.
`get_account_cart_operation`	Inspect a persisted plan or replacement belonging to the token account.
`reconcile_account_cart_operation`	Read back an uncertain token-account operation and update its journal without another remote mutation.

Inputs: credentials.username, credentials.password; the example intentionally omits both to demonstrate validation without logging in.
