MCP contract parity — measured read, 25 September 2026

Question. Does one remote MCP service tell a relying agent one current contract? A relying agent learns a service's contract from several public surfaces — the MCP Registry entry, /.well-known/mcp.json, the server card, the A2A agent card, the x402 manifest, and what the endpoint itself answers at discovery. When they disagree, the agent cannot infer which one is current. This dataset records, per endpoint and per dimension, whether they agree.

Measurement, not certification. Nothing here grades a vendor. An INCONSISTENT row says two public statements disagree and quotes both; it does not say which is right.

Our own endpoint first

The measuring estate runs the same instrument on its own endpoint (https://councilof.ai/mcp) and publishes it first:

dimension	state	quoted
VERSION	CONSISTENT
TOOLS	CONSISTENT
AUTH	CONSISTENT
PAYMENT	CONSISTENT	all 13 tools the x402 manifest names are in the live tools/list
PROTOCOL	SINGLE_SURFACE	no surface declares an MCP protocol version

Read state

EXHAUSTED — 5828 of 5828 planned endpoints attempted (EXHAUSTED only if every planned endpoint's surfaces were attempted; anything else is PARTIAL). Population: auth_required+advertises_x402_or_a2a 20, responded 5807, watch_list 1. endpoints the 25 Sep 2026 census probe saw RESPOND (top-20% and first-party plans), plus AUTH_REQUIRED endpoints whose registry entry advertises x402 or an A2A card, plus the endpoints of registry entries named in an external watch list. Counts are over attempted endpoints of this plan: not frame totals, not population totals, never summed with other censuses.

Per-dimension states (attempted endpoints)

dimension	CONSISTENT	INCONSISTENT	SINGLE_SURFACE	UNCHECKABLE
VERSION	3163	2644	21	0
TOOLS	905	233	4532	158
AUTH	931	23	4465	409
PAYMENT	112	4	572	5140
PROTOCOL	459	33	5064	272

Endpoints with at least one INCONSISTENT dimension: 2778.

UNCHECKABLE, by reason:

TOOLS: LIVE_TOOL_LIST_UNAVAILABLE 158
AUTH: DECLARED_REQUIRED_SCOPE_UNSTATED 406, DISCOVERY_NOT_AUTH_OBSERVABLE 3
PAYMENT: NO_PAYMENT_SURFACE 5140
PROTOCOL: DECLARED_VERSION_NOT_REQUESTED 248, NO_NEGOTIATED_VERSION 2, NO_PROTOCOL_SURFACE 22

Method

Surfaces, fetched GET-only from each endpoint's origin (robots.txt honoured for the product token CSOAI-census, at most one connection and one request per second per host, User-Agent CSOAI-census/0.1 (+https://councilof.ai/census)): /.well-known/mcp.json, /.well-known/mcp/server-card.json (and any server-card URL the registry entry declares), /.well-known/agent-card.json, /.well-known/x402.json, and a /health or /version URL only when the registry entry or a fetched surface names it. The registry entry comes from the census frame's full read of the official MCP Registry; the live answers (serverInfo, negotiated protocolVersion, tools/list names as a sha256) come from the same day's read-only census probe. No tool was called, no credential or payment sent.

Attribution. An origin-level document is attributed to an endpoint only if the origin serves one server in the whole census frame, or the document names the endpoint's URL. A gateway's card is not evidence about its tenants.

Dimensions.

VERSION — only claims about the same declared thing are compared. The registry schema defines server.version as "Version string for this server. SHOULD follow semantic versioning (e.g., '1.0.2', '2.1.0-alpha'). Equivalent of Implementation.version in MCP specification.", i.e. serverInfo.version. Registry, live initialize and card serverInfo.version are compared; every other version string (card top-level version, A2A agent version, x402 manifest version, /health version) is recorded in other_versions and not adjudicated. Registry version vs live serverInfo: {"differ": 2632, "equal": 3170}.
TOOLS — each declared tool list / count vs the live tools/list (sha256 of sorted names, as the probe computes it).
AUTH — declared requirements vs each other and vs the observed discovery boundary. Declared required with discovery answering without credentials is UNCHECKABLE (DECLARED_REQUIRED_SCOPE_UNSTATED): tools/call is never sent.
PAYMENT — presence parity only: tools an x402 manifest names vs the live tool list; an x402 manifest linking this endpoint vs a payment statement on an MCP surface. Silence is not a statement.
PROTOCOL — declared MCP protocol versions vs the negotiated one (conditional on the probe's request, 2025-11-25).

States: CONSISTENT, INCONSISTENT (both values quoted with surface + path), SINGLE_SURFACE, UNCHECKABLE (reason code).

HOLD watcher (version changed -> hold until re-measured)

Registry reads compared: 2026-09-25T04:40:39Z (RAS lane read, file mtime) -> 2026-09-25T05:45:50Z..05:54:05Z (census frame read), 2026-09-25T05:45:50Z..05:54:05Z (census frame read) -> 2026-09-25T11:25:23Z (frame read + updated_since fetch). Every server whose server.version changed between two reads is listed as HOLD_UNTIL_REMEASURED in hold.jsonl.gz. Servers with a remote endpoint were then re-probed (read-only, prober 0.2, bounded at 300) and recorded by name as REMEASURED_SAME or REMEASURED_CHANGED (tool-name set, auth boundary, or protocol changed vs the last census probe), or kept on hold with a reason (no remote endpoint; no earlier probe row; not attempted).

HOLD_UNTIL_REMEASURED	85
REMEASURED_CHANGED	6
REMEASURED_NO_BASELINE	14
REMEASURED_SAME	60
REMEASURE_INCONCLUSIVE	8

What this does NOT show

runtime auth enforcement beyond the discovery boundary (initialize + tools/list); tools/call is never sent
backend behaviour, tool correctness, safety, or quality of any service or vendor
which surface is right: an INCONSISTENT row says two public statements disagree, not which one is true
anything from documentation prose, except a registry description's literal mention of x402 (payment presence only)
anything about endpoints not in the plan or not attempted
simultaneity: live answers and documents were read hours apart (see timing); a deploy in between can show as INCONSISTENT

record.signed.json (Ed25519 signature, signed_at 2026-09-25T12:25:41.808Z), record.json.ots (OpenTimestamps proof), record.ots.json (its stated state). Rows carry quoted values for conflicts only; tool names appear only as sha256 digests, counts, and at most 5 differing names where a declared list and the live list disagree.

How to verify

Signature. In record.signed.json: serialise payload as JSON with keys sorted, no whitespace, UTF-8; its sha256 must equal signature.payload_sha256; payload.artifact.sha256 must equal sha256 of record.json; verify signature.sig_ed25519 (hex) with the Ed25519 key #board-attestation-1 in https://csoai.org/.well-known/did.json. Change one byte of the payload and it must fail.

import json, hashlib, base64, urllib.request
from cryptography.hazmat.primitives.asymmetric import ed25519
s = json.load(open("record.signed.json"))
c = json.dumps(s["payload"], sort_keys=True, separators=(",", ":"), ensure_ascii=False).encode()
assert hashlib.sha256(c).hexdigest() == s["signature"]["payload_sha256"]
assert hashlib.sha256(open("record.json", "rb").read()).hexdigest() == s["payload"]["artifact"]["sha256"]
did = json.load(urllib.request.urlopen("https://csoai.org/.well-known/did.json"))
x = [m for m in did["verificationMethod"] if m["id"].endswith("#board-attestation-1")][0]["publicKeyJwk"]["x"]
ed25519.Ed25519PublicKey.from_public_bytes(base64.urlsafe_b64decode(x + "==")).verify(bytes.fromhex(s["signature"]["sig_ed25519"]), c)

Timestamp. ots upgrade record.json.ots then ots verify record.json.ots. At publication the proof held 3 pending calendar attestations (https://alice.btc.calendar.opentimestamps.org, https://bob.btc.calendar.opentimestamps.org, https://finney.calendar.eternitywall.com): a pending calendar commitment, not a Bitcoin attestation.

Timestamp status

Checked 2026-09-25T13:57Z by ots upgrade on a copy of each published pending proof. A pending .ots is never rewritten: an upgraded proof is published as a NEW file <name>.bitcoin.ots beside it. BITCOIN_ATTESTED means the proof carries a BitcoinBlockHeaderAttestation whose commitment (byte-reversed) equals the merkle root of the block header at that height as served by two independent public sources (blockstream.info and mempool.space; each raw header also double-SHA256s to the block hash it is served under). No local Bitcoin node was used. Details: ots-bitcoin-check-2026-09-25.json.

record.json (sha256 45e3fd63fc98ad251a4f9fe5fdb705ed7fbc28321d5c205d10114a21730cc323): BITCOIN_ATTESTED at block 968549 (checked against 2 header sources: blockstream.info, mempool.space). Upgraded proof: record.json.bitcoin.ots (sha256 e38d524655a32a8acdca3be872165b3933dbfcdff8ea1ca3354d61a7f6d2e989); the published pending proof record.json.ots is unchanged.

Corrections

0.1.1 — 26 September 2026 (supersedes `record.json` 0.1; the 0.1 files stay published unchanged)

record.v0.1.1.json (sha256 9cd02be424bf608d41f40522e48188f5a9ef4d13c8de6e28023b20a941fd4ef8) supersedes record.json (sha256 45e3fd63fc98ad251a4f9fe5fdb705ed7fbc28321d5c205d10114a21730cc323). Scope: reclassification only: same plan, same stored surface fetches, same hold re-probe; no new network read. The rows are rows.v0.1.1.jsonl.gz; rows.jsonl.gz, record.json, record.signed.json, record.json.ots and record.ots.json are kept byte for byte: superseded, not deleted, not edited.

Why. the 26 Sep 2026 notice lane re-checked candidates live before any contact and found that the 0.1 rows for immersivecommons (TOOLS), augenix (TOOLS) and klarix (AUTH) misread the service, and that transloadit (AUTH) and toolforte (TOOLS) held reasonable different meanings. All five were INCONSISTENT in 0.1. Reproduced from the stored 25 Sep bytes (each document's sha256 unchanged on the 26 Sep re-read): correction.v0.1.1.evidence.json.

What was wrong, and the fix (producer scripts/census/contract-parity.py 0.1.1, commit 4037f6bb2b7162b1679301846287b95934a85ad6):

D1 (TOOLS). 0.1: every declared tool list was compared exactly with the live tools/list. Why wrong: the live tools/list is read WITHOUT credentials. A service that names the tools usable without credentials (public_tools, anonymousTools, ...) declares that its unscoped list is its full, partly authenticated surface; an unauthenticated listing may show the public subset or everything. The full list is not a claim about what unauthenticated discovery lists. 0.1.1: with a public-scoped list present, unscoped lists / counts are compared as supersets (every live tool must be in them); the public list is recorded, not compared (it scopes use, not listing).
D2a (attribution (all)). 0.1: an origin's documents were credited to an endpoint whenever the census frame knew one server on that origin. Why wrong: the document itself can say it describes another endpoint mount on the same origin; the origin then serves more than one MCP endpoint and the instrument's own shared-origin rule applies 0.1.1: an MCP document naming another endpoint mount on this origin (and not this endpoint) is not credited; another host (www/apex, a custom domain) or another transport/version path of the same mount is not read as a second endpoint.
D2b (attribution (all)). 0.1: facts were read from every nested block of a credited document. Why wrong: a nested block with its own url and its own tools/transport describes another endpoint (a docs MCP, an apps MCP, a hosted demo) 0.1.1: such a block is removed before facts are read: always when its endpoint is on this origin; on another host only when the document also describes an endpoint of its own outside the block.
D3 (AUTH). 0.1: a registry remote header with isRequired false and a card's authentication.required true were paired as a contradiction. Why wrong: isRequired false (the registry omits false; the schema default is false) says the client may CONNECT without the header; the card's 'required' does not say whether it applies to discovery or to tools/call. Two claims of different scope; tools/call is never sent, so which scope the card means is not observed. 0.1.1: UNCHECKABLE (DECLARED_SCOPES_DIFFER); still INCONSISTENT when discovery itself was refused without credentials.
D4 (TOOLS). 0.1: a bare declared tool count was compared with the live tool count. Why wrong: when the live list holds a dispatcher (run_tool, call_tool, ...), a count above the live count may count tools reached through it; the count does not say which it counts 0.1.1: not compared; UNCHECKABLE (DECLARED_COUNT_SCOPE_UNSTATED) when it is the only declared figure; a count BELOW the live count is still INCONSISTENT.

Check. the 0.1 producer (commit d9e0f80) re-run over the same inputs reproduces all 5828 published 0.1 rows byte-identically, so every difference below is the producer change and nothing else. Tests: scripts/census/test_contract_parity.py class Correction011: one fixture per reported case, shapes copied from the stored bytes; five must-fail controls, each restoring one 0.1 rule, fail the suite.

Rows that change state: 22 endpoints, 26 dimension states.
