\n\n---\n\n## Tools\n\nSix tools covering the full IMF SDMX 3.0 query workflow, plus a DuckDB-backed canvas layer for SQL analytics over large multi-country result sets:\n\n| Tool | Description |\n|:-----|:------------|\n| `imf_list_databases` | List IMF SDMX dataflows available on the portal, a page at a time, with optional name/ID/description substring filtering |\n| `imf_get_database` | Fetch a dataflow's dimensions and page either its codelists or the codes with published data — resolves human terms to SDMX codes before querying |\n| `imf_query_dataset` | Query a dataflow by dimension key over a time range; large result sets spill to DataCanvas |\n| `imf_dataframe_describe` | List DataCanvas tables and columns staged by a prior `imf_query_dataset` call |\n| `imf_dataframe_query` | Run a read-only SQL SELECT across staged DataCanvas tables for multi-country comparisons and aggregations |\n| `imf_dataframe_drop` | Remove one staged table or view without affecting other tables on the canvas; disabled by default |\n\n### `imf_list_databases`\n\nEntry point for every IMF query workflow — browse and filter the dataflow catalog, a page at a time.\n\n- Hundreds of dataflows covering WEO projections, balance of payments, CPI, exchange rates, money/finance statistics, and national accounts\n- Vintage (historical snapshot) dataflows excluded by default; set `include_vintages=true` to include them\n- Case-insensitive substring filter across ID, name, and description — matched against the full description, not the shortened one returned\n- Paged: `limit` (default 50, max 200) and `offset`. `total_count` is the number of matches, `returned_count` the size of the page, and a notice names the next `offset` while matches remain\n- Descriptions are cut to 200 characters here; `imf_get_database` and the `imf://database/{dataflow_id}` resource return the full text for the dataflow you settle on\n\n---\n\n### `imf_get_database`\n\nResolve human-readable terms to SDMX dimension codes before querying.\n\n- Returns every dimension ID, its position, its label from the DSD concept scheme (`WGT_TYPE` → `Weight Type`), and a codelist preview (e.g. `\"United States\"` → `USA`, `\"Constant prices\"` → `NGDP_RPCH`)\n- Country codes are ISO 3-letter (USA, GBR, DEU — not US, GB, DE)\n- `key_format` field shows the exact dot-separated dimension order required by `imf_query_dataset`\n- Every codelist preview is bounded at 50 entries, including substring-filtered previews. Set `dimension_id` to page one codelist with `limit`/`offset`; `codelist_filter` still applies its case-insensitive substring match before paging\n- Set `available_only=true` to replace codelists with codes reported by the dataflow-wide availability constraint. The response includes total series and time coverage, joins each available code to its DSD label with an ID fallback, and applies `dimension_id`, `codelist_filter`, `limit`, and `offset` after availability filtering. Omit `dimension_id` for a bounded preview of every structure dimension, including empty dimensions the constraint does not mention\n- A filter that matches nothing is reported distinctly from a codelist that could not be resolved — the two need opposite next steps\n\n---\n\n### `imf_query_dataset`\n\nQuery an IMF SDMX dataflow by dimension key over a time range.\n\n- Dot-separated key in DSD keyPosition order (e.g. `USA.NGDP_RPCH.A` for WEO annual GDP at constant prices, percent change)\n- `+` combines codes at one position (e.g. `USA+GBR+DEU.NGDP_RPCH.A`); `*` matches every code at a position (`*.NGDP_RPCH.A` for all countries, `CAN.*.A` for every indicator). Every position needs a code or a `*` — a blank segment matches nothing upstream and is rejected\n- `start_period` / `end_period` accept `YYYY`, `YYYY-SN`, `YYYY-QN`, `YYYY-MM`, or a calendar-valid `YYYY-MM-DD` whatever the series frequency, and cover the whole period they name — `end_period: 2023` includes `2023-M12` and `2023-Q4`\n- Returns observations with `time_period`, `value`, `status`, and series attributes (`unit`, `scale`, `decimals`). Period labels come back as upstream emits them — `2023`, `2023-S1`, `2023-Q1`, `2023-M01`, `2023-01-05` — and any of them can be passed straight back in as a bound\n- A key resolving to several series carries `series_metadata`, one `unit`/`scale`/`decimals` entry per `series_key`, because attributes differ between them: in `USA.NGDPD+NGDP_RPCH.*`, `NGDPD` is `USD` at scale `9` while `NGDP_RPCH` is `PT` and unscaled. Canvas rows carry their own series' attributes too. A single-series query keeps the flat `series_attributes` and no list\n- `unit` is the upstream code — `PT`, `USD`, `XDC`, `IX`, `NUM`. Every key shape reports the same unit: the portal drops the unit block when a key uses `+` on the dimension that carries it, and one extra attributes-only request recovers it, so `USA.NGDP_RPCH+NGDPD.A` and `USA.NGDP_RPCH+NGDPD.*` both report `USD` and `PT`. That key shape is the only one that costs the second request; every other query makes one. A `unit: null` therefore means the dataflow publishes none, which many do\n- Scale `0` is the upstream sentinel for \"no multiplier\" — formatted output names it rather than printing a bare `0`, and `structuredContent` keeps the raw code\n- Large multi-country or long time-range queries automatically spill to DataCanvas; set `output_mode: \"canvas\"` to explicitly stage any result, using `canvas_id` as the destination when supplied\n- `staged` reports whether the complete result is on DataCanvas; `truncated` reports only whether `observations` is an incomplete preview. Staged results always return `canvas_id`, `table_name`, and describe-before-query guidance in both MCP result channels\n- `no_data` errors include availability context from the upstream constraint endpoint: a dataflow that publishes no series at all is reported as such and points at a different dataflow, since no key would work; otherwise `series_count=0` means the code has no coverage and `dataflow_availability` names codes that do, while `series_count>0` means the combination is wrong and `available_codes` lists what does have data per dimension, stating how many of how many it is showing when a dimension is too long to list in full\n- A valid key whose data lies entirely outside the requested range fails as `no_data_in_range`, reporting the range the series actually spans — the fix is the range, not the key\n\n---\n\n### `imf_dataframe_describe` / `imf_dataframe_query` / `imf_dataframe_drop`\n\nIn-conversation SQL analytics over the observation tables that `imf_query_dataset` stages on a DuckDB-backed canvas.\n\nWhen `imf_query_dataset` returns `staged: true`, the full dataset is registered as a named table on the canvas. The workflow:\n\n1. Call `imf_query_dataset` — let large results spill automatically or set `output_mode: \"canvas\"`; when `staged: true`, note the `canvas_id` and `table_name`\n2. Call `imf_dataframe_describe` with the `canvas_id` to discover table schema\n3. Call `imf_dataframe_query` with a SELECT statement for aggregations, cross-country comparisons, or time-series analysis\n4. When table cleanup is enabled, call `imf_dataframe_drop` with a name from `imf_dataframe_describe` to remove only that table or view\n\nOne SELECT statement per call; a leading `WITH … SELECT` common table expression is accepted. DML and DDL are rejected. DataCanvas first caps materialization at its row limit (default 10,000), then the server retains the largest row prefix whose complete structured and formatted response fits 100,000 serialized characters. `row_count` always equals the returned rows; `truncated: true` means either cap omitted rows, and the remainder is reachable with a stable `ORDER BY` plus `LIMIT`/`OFFSET`. If one row cannot fit, `response_too_large` asks the caller to select fewer columns, aggregate, or shorten values. Requires `CANVAS_PROVIDER_TYPE=duckdb`.\n\n`imf_dataframe_drop` is opt-in because it mutates the canvas. Set `IMF_ENABLE_DATAFRAME_DROP=true` to register it in `tools/list`; disabled HTTP deployments retain the exact enable hint in the HTML landing-page inventory. The SEP-1649 discovery document at `/.well-known/mcp.json` does not enumerate tool definitions. A successful removal returns `dropped: true`; an absent or previously removed name returns `dropped: false` while leaving the canvas and its other tables intact.\n\n## Resource\n\n| Type | URI | Description |\n|:-----|:----|:------------|\n| Resource | `imf://database/{dataflow_id}` | Bounded discovery metadata for a single IMF SDMX dataflow — all dimensions with up to 50 codelist entries each, counts, `key_format`, name, description, and continuation metadata. |\n\nThe resource stays bounded and points machine-readably to `imf_get_database` for continuation. To retrieve a large codelist, call `imf_get_database` with its `dimension_id`, then follow `next_offset` with `limit`/`offset`; add `codelist_filter` to page only entries whose ID or name contains a substring.\n\n## Data source\n\nData is sourced from the [International Monetary Fund SDMX 3.0 portal](https://data.imf.org/) under the [IMF Copyright and Terms of Use](https://www.imf.org/en/about/copyright-and-terms). The IMF's terms permit redistribution of statistical data with attribution. Each data-returning tool response includes a `source` field with the required attribution: `Source: International Monetary Fund, , https://data.imf.org/`.\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool, resource, and prompt definitions — single file per primitive, framework handles registration and validation\n- Unified error handling — handlers throw, framework catches, classifies, and formats\n- Pluggable auth: `none`, `jwt`, `oauth`\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- STDIO and Streamable HTTP transports\n\nIMF SDMX-specific:\n\n- Keyless access — no API key required; the IMF SDMX 3.0 portal is fully public\n- Type-safe SDMX 3.0 compact JSON client with dimension/codelist parsing and DSD validation\n- Key dimension count validated against the DSD before each query to catch format mismatches early\n- Dataflow catalog and full availability constraints cached in-session to minimize round trips on multi-step workflows\n- DuckDB-backed DataCanvas spill for large multi-country or long time-range observations\n\nAgent-friendly output:\n\n- Codelist entries carry both the machine code and human-readable label — agents can present meaningful names without a follow-up lookup\n- `key_format` field in every dataflow response explicitly states the dimension order, removing guesswork for key construction\n- Observations include `status` flags (e.g. `E` for estimate) so agents can communicate data quality caveats\n- Canvas placement is explicit — `staged` distinguishes storage from `truncated` preview completeness, and staged results carry `canvas_id`, `table_name`, and retrieval guidance\n\n## Getting started\n\n### Public Hosted Instance\n\nA public instance is available at `https://imf.caseyjhand.com/mcp` — no installation required. Point any MCP client at it via Streamable HTTP:\n\n```json\n{\n \"mcpServers\": {\n \"imf-mcp-server\": {\n \"type\": \"streamable-http\",\n \"url\": \"https://imf.caseyjhand.com/mcp\"\n }\n }\n}\n```\n\n### Self-Hosted / Local\n\nNo API key required. Add the following to your MCP client configuration file.\n\n```json\n{\n \"mcpServers\": {\n \"imf-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"bunx\",\n \"args\": [\"@cyanheads/imf-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\"\n }\n }\n }\n}\n```\n\nOr with npx (no Bun required):\n\n```json\n{\n \"mcpServers\": {\n \"imf-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"npx\",\n \"args\": [\"-y\", \"@cyanheads/imf-mcp-server@latest\"],\n \"env\": {\n \"MCP_TRANSPORT_TYPE\": \"stdio\",\n \"MCP_LOG_LEVEL\": \"info\"\n }\n }\n }\n}\n```\n\nOr with Docker:\n\n```json\n{\n \"mcpServers\": {\n \"imf-mcp-server\": {\n \"type\": \"stdio\",\n \"command\": \"docker\",\n \"args\": [\n \"run\", \"-i\", \"--rm\",\n \"-e\", \"MCP_TRANSPORT_TYPE=stdio\",\n \"ghcr.io/cyanheads/imf-mcp-server:latest\"\n ]\n }\n }\n}\n```\n\nTo enable SQL analytics over large result sets, add `CANVAS_PROVIDER_TYPE=duckdb` to the `env` block. Add `IMF_ENABLE_DATAFRAME_DROP=true` only when agents should be able to remove staged tables.\n\nFor Streamable HTTP, set the transport and start the server:\n\n```sh\nMCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http\n# Server listens at http://localhost:3010/mcp\n```\n\n### Prerequisites\n\n- [Bun v1.3.0](https://bun.sh/) or higher (or Node.js v24+).\n- No API key required.\n\n### Installation\n\n1. **Clone the repository:**\n\n```sh\ngit clone https://github.com/cyanheads/imf-mcp-server.git\n```\n\n2. **Navigate into the directory:**\n\n```sh\ncd imf-mcp-server\n```\n\n3. **Install dependencies:**\n\n```sh\nbun install\n```\n\n4. **Configure environment:**\n\n```sh\ncp .env.example .env\n# edit .env as needed — no required vars for basic use\n```\n\n## Configuration\n\n| Variable | Description | Default |\n|:---------|:------------|:--------|\n| `CANVAS_PROVIDER_TYPE` | Set to `duckdb` to enable DataCanvas spill for large result sets. | — |\n| `IMF_ENABLE_DATAFRAME_DROP` | Advertise and enable destructive table-level DataCanvas cleanup. | `false` |\n| `IMF_BASE_URL` | IMF SDMX 3.0 base URL.
