MCP / playground

33 Cosmos stack tools live on https://cosmopedia.xyz/mcp. Try any of them in the browser. Same endpoint that Claude Desktop / Cursor / Windsurf would connect to. Each call is a real tools/call JSON-RPC request proxied through this site.

search

Keyword/full-text search over the Cosmopedia Cosmos knowledge base (forum, docs, GitHub, releases, security advisories, Hub governance proposals, ADR/RFC/ICS specs, whitepapers, videos). Cosmos stack only, unofficial. Do NOT use for other blockchains, the web, or local files. Use this for exact-term, name and identifier lookups; use semantic_search for conceptual or 'how does X work' questions, and get_doc to read a full page.

Arguments

query*stringSearch querytypestring · default: allRestrict results to one source type; "all" searches everythinglimitinteger · default: 10Max results to return. Default 10, max 50.offsetinteger · default: 0Skip this many before returning, for paging past the limit. The response states the full count and echoes the offset used.

Calls POST /mcp through our proxy. ~2-5s typical.

Connect from your agent client

Point any MCP client at https://cosmopedia.xyz/mcp (no auth) and the same 33 tools become available in the chat. Copy-paste configs for Claude Desktop, Claude Code, Cursor, VS Code, Zed, JetBrains, ChatGPT and more are on /for-ai, the single setup reference.

What this is NOT

Not a replacement for connecting your client. The playground is a demo surface so you can see what each tool returns before committing to the config step. For day-to-day use, point Claude Desktop / Cursor at https://cosmopedia.xyz/mcp.
Not unlimited. Each call goes through our regular MCP rate limit. The playground is for exploration, not stress-testing. If you need high-volume programmatic access, use the REST API or run an agent.
Not a code generator. The JSON-RPC payload block shows the exact shape, but you still need to send it from your MCP client. Cosmopedia doesn't generate code for your stack.
