Nothing serious here today

Today is the operative word: we check Oecd MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 14 min ago.

This one needs environment variables set before it will start: MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').). The author declared them in the registry entry; get the values from the project itself.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

oecd
oecd_dataframe_describe
List tables and columns staged on a DataCanvas by a prior oecd_query_dataset spill. Call this before oecd_dataframe_query to discover exact table and column names for SQL. Only available when CANVAS_PROVIDER_TYPE=duckdb is set.
oecd_dataframe_query
Run a read-only SQL SELECT against OECD observation tables staged on a DataCanvas by oecd_query_dataset. Call oecd_dataframe_describe first to discover exact table and column names, then use this tool for aggregation, filtering, GROUP BY, JOIN, and window functions. Only available when CANVAS_PROVIDER_TYPE=duckdb is set.
oecd_get_dataset_info
Fetch a dataflow's dimensions, their order, and how to construct a query key. Returns per-dimension names, codelist references, and position in the dot-delimited key. Required before calling oecd_query_dataset to understand key structure.
oecd_get_dimension_values
Fetch the valid codes and labels for one dimension of a dataflow. Use to resolve human-readable names (countries, measures) to SDMX codes before querying with oecd_query_dataset. Pass query to match a code or label by substring — codelists run to a thousand-plus entries, and the response is a page of at most limit codes either way.
oecd_list_agencies
List OECD SDMX agencies, the directorate each belongs to, and the number of dataflows each publishes. Use to discover agency IDs before filtering oecd_search_datasets by department.
oecd_query_dataset
Fetch observations from an OECD dataflow filtered by a dimension key and optional time range. Returns decoded rows (one per observation) with dimension and attribute labels, and values already scaled by the observation unit multiplier. Large multi-country time-series spill to a DataCanvas table — follow up with oecd_dataframe_query; without DataCanvas every row still comes back, but the rendered table stops at a preview slice. Call oecd_get_dataset_info first to learn the dimension order for constructing the key.
oecd_search_datasets
Search OECD dataflows by keyword or theme, matching against dataflow names and descriptions. Returns flow_ref identifiers, names, and agency IDs for use with oecd_get_dataset_info.

Oecd MCP Server — questions

Answers built from our own checks of this server.

What can Oecd MCP Server do?
It exposes 7 tools, read directly from the server on our last check. Among them: oecd_dataframe_describe, oecd_dataframe_query, oecd_get_dataset_info, oecd_get_dimension_values, oecd_list_agencies, oecd_query_dataset and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Oecd MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 384 ms. The bar chart above shows every period we have measured.
How do I connect Oecd MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Oecd MCP Server need an API key?
No. Oecd MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Oecd MCP Server?
It answers our handshake in 384 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Oecd MCP Server?
The npm package @cyanheads/oecd-mcp-server was installed 96 times in the last week. Week over week that is +51%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Oecd MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 2 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
