Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

13 of 13 tools

Documented tools (13)

From project documentation. A server handshake does not verify each tool’s description or behavior.

opendata_domains_list

Enumerate the controlled domain vocabulary (health, legal, finance, earth-science, …).

opendata_explain_choice

Show the scoring breakdown for a search (useful for debugging routing decisions).

opendata_health_snapshot

Return per-provider health scores used by discovery health badges and routing context.

opendata_plugins_create

Autonomously create a new plugin. Takes a YAML spec (typically produced by opendatapluginsdraft), runs the generator, imports the new module, registers it in the live registry, and hot-loads its tools onto the running server. Use this when opendataprovidersfind returns no match.

opendata_plugins_draft

Build a validated plugin YAML spec from structured inputs. Takes id, baseurl, tool definitions (name, endpoint, params), and registry metadata. Validates id/tool-name casing, path-placeholder/param consistency, and parameter types, then emits a YAML string ready to feed into opendatapluginscreate. U

opendata_providers_activate

Activate one provider so its tools become callable in this session.

opendata_providers_deactivate

Remove an activated provider's tools from the current session catalog.

opendata_providers_describe

Full metadata for one plugin by id — title, description, domains, regions, keywords, homepage, required env vars.

opendata_providers_find

Free-text search over the plugin registry. Returns ranked matches. When nothing matches the response carries a nomatch: true flag and a nextstep hint pointing at opendatapluginsdraft + opendatapluginscreate.

opendata_providers_list

Paginated dump of the whole registry.

opendata_providers_list_active

List currently active providers and the tool names each contributes.

opendata_regions_list

Enumerate the controlled region vocabulary (us, eu, uk, global, …).

opendata_tool_call

Proxy-call an activated plugin tool by name for environments that cannot directly invoke dynamically added tools.

Questions about Meta Data MCP Server

How do I connect Meta Data MCP Server to Claude?

Is Meta Data MCP Server free?
The listed licence is MIT. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.
What can Meta Data MCP Server do?
Meta Data MCP Server documents 13 tools to the agent, including opendata_domains_list, opendata_explain_choice, opendata_health_snapshot. The descriptions above come from project documentation. A live handshake does not test individual tool behavior.
