BlueCat Integrity MCP Server (formerly bammcp)
The current version, v26.1.0, was published to the official MCP registry on 2026-09-24. It is distributed as the Docker image quay.io/bluecat/integritymcp@sha256:1b38c5fc9321ced181e414b82873a705a46b80c28209227e39fea4578e7a3a0d, filed under Other by this index, and declares 15 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less
uv tool install mcpindex-gate && mcpindex-config-wireVerdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-09-25).
Contracts can change after screening, with no version bump. The gate pins com.bluecat/integritymcp’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

BAM_BASE_URLBAM base URL (e.g., https://bam.bluecat.com).
BAM_USERNAMEBAM service-account username. Required unless the SSO pair (BAM_SSO_USERNAME + BAM_SSO_PASSWORD) is used instead — the server needs exactly one of the two pairs.
BAM_PASSWORDBAM service-account password. Required alongside BAM_USERNAME, unless the SSO pair is used instead.
BAM_SSO_USERNAMEBAM SSO username. Alternative to BAM_USERNAME + BAM_PASSWORD; the server needs exactly one of the two pairs.
BAM_SSO_PASSWORDBAM SSO password. Required alongside BAM_SSO_USERNAME when using the SSO pair.
MCP_AUTH_MODEClient authentication mode for the /mcp endpoint. One of: none | static-key | signed-key | resource-server. Required at runtime — the server refuses to start without it (no default).
MCP_API_KEYStatic bearer token clients present as `Authorization: Bearer <key>`. Required only when MCP_AUTH_MODE=static-key.
MCP_REQUEST_STATE_KEYHMAC key (at least 32 bytes) sealing the approval-gated write tools' requestState on MCP 2026-07-28 connections (#1031). Optional: unset uses a random per-process key, which is fine for a single replica; set the same value on every replica of a multi-replica deployment.
MCP_REQUEST_STATE_KEY_PREVIOUSSecond requestState HMAC key, accepted for opening a sealed plan but never for sealing one: two-key rotation of MCP_REQUEST_STATE_KEY (#1032). Optional, and only valid together with MCP_REQUEST_STATE_KEY. When rolling the key across replicas set this to the old key, and remove it two minutes after the last replica restarted.
MCP_ED25519_PUBLIC_KEYEd25519 public key (base64url) that MCP_AUTH_MODE=signed-key verifies license tokens against. DEFAULTS TO A SHARED DEMO KEY, which authenticates a token holder rather than a customer — every BlueCat-issued token for this server verifies against it. For anything beyond a trial, generate a per-deployment key pair (license-keygen --gen-key) and set this to its public half.
MCP_SIGNED_KEY_AUDIENCEWhen set, a license token must carry exactly this audience or it is rejected — a declarative scope check on top of the key, so a token minted for another deployment fails even if it verifies. Unset means the aud claim is not checked. Only meaningful with MCP_AUTH_MODE=signed-key.
MCP_OAUTH_ISSUERToken issuer URL, matched against the iss claim of incoming JWTs. Required when MCP_AUTH_MODE=resource-server — the server refuses to start in that mode without it.
MCP_OAUTH_JWKS_URIJWKS endpoint whose public keys verify the signature on every incoming Bearer JWT. Required when MCP_AUTH_MODE=resource-server — the server refuses to start in that mode without it.
MCP_OAUTH_AUDIENCEExpected JWT aud claim for MCP_AUTH_MODE=resource-server. A token carrying a different audience, or no aud claim at all, is rejected. Unset skips audience validation entirely.
ACCEPT_EULASet to Y (or Yes/YES, any casing) to accept the BlueCat End User License Agreement. The container refuses to start without it.
