Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Index Agentica (https://indexagentica.com) is an agent-first directory of skills, agent harnesses, MCP servers, tools, protocols, APIs, information sources, finance/payment rails and other directories, plus long-form guides, comparisons, stacks and downloadable Agent Skills. Use `search` to find resources by keywords, type (entry, guide, comparison, stack, skill), category and tags; `get_entry` for the full record of one directory entry; `get_content` (type + id) for a guide, comparison, stack or skill with its markdown; `list_categories` for the category slugs and counts; `request_listing` to ask for something missing to be added (verified by the Curator before listing). Directory data is read-only, refreshed from the published site every ~10 minutes, and licensed CC BY 4.0. To add or correct an entry, see https://indexagentica.com/agents/#contribute.

search — Search Index Agentica
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search Index Agentica: the directory of agent-usable resources (skills, harnesses, MCP servers, tools, protocols, APIs, information sources, finance/payments, directories) plus its long-form content (guides, comparisons, stacks and downloadable Agent Skills). Matches the query words against name/title, id, tags, summary and description and returns the best matches first, each with its type, a relevance score and links (HTML, markdown, JSON). Optionally filter by type (entry, guide, comparison, stack, skill; default all), category (entries only) and/or tags (ALL given tags must match). An empty query with a filter lists everything in that filter. For full details use get_entry for type entry, or get_content with the type and id for long-form items.

Fetch one Index Agentica entry by its id (kebab-case slug, e.g. "model-context-protocol"). Returns every field: name, category, summary, description, url, repo, docs, tags, license, pricing, status, agent_access (llms_txt, openapi, mcp_endpoint, auth), related ids, sources, dates and links. If the id is unknown the result is an error with suggested ids.

Advertised by the server during the last successful anonymous check.

Ask Index Agentica to add something that is missing (a skill, agent harness, MCP server, tool, protocol, API, ...). Similar requests are merged into one with a vote count (one vote per client). Nothing is listed automatically: the Curator verifies each request first. The public queue is at https://mcp.indexagentica.com/v1/requests and https://indexagentica.com/requested/. Limits: 5 requests per hour and 20 per day per client. Search first to check it is not already listed.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http index-agentica-mcp https://mcp.indexagentica.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add index-agentica-mcp --url https://mcp.indexagentica.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable index-agentica-mcp in your MCP settings.

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start index-agentica-mcp and inspect its tools.

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
