csoai/mcp-census

MCP server census

DISCOVERED — read-only census of the public MCP (Model Context Protocol) server ecosystem. Keyless registry listing + MCP handshake initialize + tools/list only — never tools/call. Nothing published to any stranger server. The live board is GET https://councilof.ai/api/gspc. 

Turned inward first. The first measured MCP entry is our own surface: councilof.ai/mcp — server csoai-gspc-mcp, 7 tools (board_totals get_axis verify_card list_cards get_root get_card verify_inclusion), all with valid inputSchema. Also

Registries censused

• —modelcontextprotocol.io (official, keyless): 2,000 server records fetched (cursor-paginated, bounded); 455 carry a resolvable remote URL.
• —Smithery (keyless): 11,191 servers reported; 300 sampled.
• —Glama: endpoint requires an API key → DISCOVERED, not probed.
• —PulseMCP: v0beta is sunsetting (random-fail), v0.1 path not resolvable keyless → noted.

Probe result (mcp_census.json)

• —41 servers probed (ours first + a 40-server sample from the official registry's resolvable remote URLs). Handshake initialize + tools/list only.
• —21 LIVE / 20 DEAD → live-fraction 0.512. 20 of the LIVE servers returned a schema-valid tool list. Roughly half of registry-listed remote MCP servers actually answer an MCP handshake.

Files

• —mcp_census.jsonl — flat viewer table, one row per probed server (41): server_id, server_name, source_registry, url, probe_state (LIVE/DEAD), tool_count, schema_valid, as_of. Nested tool-name lists live in mcp_census.json, not this table.
• —mcp_census.json — registries, per-server three-state (reachable / tool-count / schema-valid).
• —mcp_live_atoms.json — the LIVE servers with a readable, schema-valid tool list.
• —ledger-card-mcp-server-unsigned.json — the mcp.server card-v0 atom (sig_ed25519=null — NOLAPTOPSIGN, queued for GHA OIDC signing).

What this is not

• —No tools/call was ever issued. Tool correctness is unmeasured[].
• —Auth-gated servers were not bypassed. Uptime is a single-point read, not monitored.
• —Not a GSPC axis. No GSPC measure fields on any card.

GET https://councilof.ai/api/gspc — quote totals.public_count. This Hub card is a printer of that GET, never a second engine. If the fetch fails the honest answer is UNCHECKABLE — never a fabricated 0.000. Status words: LOADING / UNREACHABLE / UNMEASURED / UNCHECKABLE.
