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.

Historical own-server probe (1 September 2026). The first server probed was our own councilof.ai/mcp surface. The frozen sample records 7 tools at that time (board_totals get_axis verify_card list_cards get_root get_card verify_inclusion), all with valid inputSchema in that one probe. See the dated current readback below for its present tool list.

Current public readback — 2026-09-25T04:15:15Z

The dated machine-readable readback records a fresh POST https://councilof.ai/mcp tools/list: 13 named tools. The separate live GET https://councilof.ai/api/gspc returned 23 declared axes, 23 measured. Both exact response digests and the tool names are in that JSON; re-fetch the endpoints for later state.

The original mcp_census.json, mcp_census.jsonl and registry figures below are a 1 September 2026, 41-server historical sample. Its own-server row correctly records seven tools then. Lower 22-axis and 12-tool statements were dated prior reads and are superseded for current use. This update did not re-probe the other 40 servers, call tools, measure correctness, sign or anchor a result, or establish adoption.

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 — NO_LAPTOP_SIGN, 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.

The live board is the authority

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.

Historical lid (4 September 2026): 22 axes measured · 14 model fleets · 3 public leader scores · 8 fact runs. Superseded for current use by the dated live-board readback above.
