For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/quivermutationdb-mcp-ecd7cb9b30
GET https://www.mcpbundles.com/api/directory/v1/servers/quivermutationdb-mcp-ecd7cb9b30?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/quivermutationdb-mcp-ecd7cb9b30/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/quivermutationdb-mcp-ecd7cb9b30/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Get Stats — Dataset totals and, per rank, how the data was generated (weight bound, node cap, pipeline version, date).
Search Quivers — Filter, sort and page quivers. Returns items with exchange_matrix and class summary plus next_cursor. scope=labelings returns one row per labeled exchange matrix (default sort only). Counting a filtered cut of a 42.5M-row rank is a full scan, so by default the count stops at 10,000 and the response sets total_is_lower_bound: true; pass total='exact' only when you need the true figure. Page with next_cursor rather than inferring page count from total.
Get Bulk Corpus — Where to download the ENTIRE census as files (gzipped NDJSON per rank, sha256-checksummed, resumable, free egress). Use this instead of paging search_quivers or /export.ndjson when the goal is the whole dataset or a whole rank -- rank 6 alone is 42.5M rows. Returns file names, row counts, sizes and URLs.
Get Quiver — One quiver by id (Q.n{rank}.{hash}): canonical exchange matrix, invariants, class summary.
Get Quiver Labelings — Every labeled exchange matrix of a quiver within its mutation class (paged).
List Classes — Filter, sort and page mutation classes (with nickname, exploration state, three-state properties).
Get Class — One mutation class by id (MC.n{rank}.{hash}) or curated nickname slug (e.g. markov): invariants with three-state values, provenance/witnesses, canonical matrix, first page of distinct member quivers.
List Class Members — Members of a mutation class, paged: kind=distinct (one per unlabeled quiver, canonical first) or kind=labelings (every labeled exchange matrix in orbit order; qmd_id restricts to one quiver).
Lookup Quiver — Find the quiver a skew-symmetric exchange matrix represents: returns its canonical (lex-min) matrix and Q.* id, and the database row if the census contains it (found=false otherwise). b_ij > 0 means b_ij arrows i -> j.
