Data Prism
Privacy layer for enterprise APIs; refuses to start without a reviewed adapter jar per source
The current version, v0.2.0, was published to the official MCP registry on 2026-09-17. It is distributed as the Docker image ghcr.io/aindriub/data-prism-server:0.2.0, filed under Other by this index, and declares 21 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 2026-09-18).
Contracts can change after screening, with no version bump. The gate pins Data Prism’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

LOADER_PATHDirectory Spring Boot's PropertiesLauncher scans for extension jars; already set to /app/adapters by the image, but startup still fails with MISSING_SOURCE_ADAPTER until you bind-mount a reviewed DataSourceAdapter/IdentityResolver jar there (see the -v arguments above)

DATAPRISM_SECURITY_JWT_AUDIENCEExpected JWT audience claim for this deployment; required for every protected deployment
DATAPRISM_SECURITY_JWT_JWK_SET_URIHTTPS JWKS location used to verify caller JWTs; exactly one of this or DATAPRISM_SECURITY_JWT_ISSUER_DISCOVERY_URI is required, never both
DATAPRISM_SECURITY_JWT_ISSUER_DISCOVERY_URIAlternative HTTPS OIDC issuer-discovery location; set this instead of DATAPRISM_SECURITY_JWT_JWK_SET_URI, never both
DATAPRISM_SECURITY_CALLER_CLAIMS_PRINCIPALJWT claim name that carries the caller's principal identifier; required, must differ from the roles and investigation claims
DATAPRISM_SECURITY_CALLER_CLAIMS_ROLESJWT claim name that carries the caller's roles; required, must differ from the principal and investigation claims
DATAPRISM_SECURITY_CALLER_CLAIMS_INVESTIGATIONJWT claim name that carries the trusted investigation/case identifier; required, must differ from the principal and roles claims
DATAPRISM_SECURITY_POLICY_PURPOSESComma-separated list of permitted purposes; at least one is required
DATAPRISM_SECURITYPOLICY_ROLES_INVESTIGATORExample only — declare DATAPRISM_SECURITYPOLICY_ROLES_<ROLE> per operator-defined role (no underscore between SECURITY and POLICY: Spring Boot's map-key enumeration under a hyphenated dataprism.security-policy.roles.<role> segment only binds the concatenated prefix, verified by binding this property directly against Spring Boot 3.5.16), a comma-separated list of known MCP tool capabilities; at least one role-to-capability mapping is required
DATAPRISM_PRIVACY_PROFILEName of the reviewed privacy profile implementation to apply; required
DATAPRISM_PRIVACY_SCOPE_LIFETIMEPositive duration (e.g. 8h) a privacy scope's synthetic identities remain valid; required
DATAPRISM_PRIVACY_HMAC_KEY_KEY_IDIdentifier of the pinned HMAC key used to derive synthetic identities; required
DATAPRISM_PRIVACY_HMAC_KEY_ENVIRONMENT_VARIABLEName of the environment variable holding the HMAC key material; exactly one of this or DATAPRISM_PRIVACY_HMAC_KEY_PROVIDER_REFERENCE is required, never both, and never a literal key value
DATAPRISM_PRIVACY_HMAC_KEY_PROVIDER_REFERENCEReference to an approved secret provider holding the HMAC key material; set this instead of DATAPRISM_PRIVACY_HMAC_KEY_ENVIRONMENT_VARIABLE, never both
DATAPRISM_AUDIT_SINKAudit sink implementation: one of approved-sink, slf4j, hash-chained; required, never downgraded to no-op
DATAPRISM_AUDIT_WRITER_IDWriter/instance identity recorded on every audit entry; required
DATAPRISM_METRICS_SINKMetrics sink binding, currently only micrometer; required in production, never the framework no-op
DATAPRISM_HAZELCAST_TOPOLOGYCluster read-budget topology: embedded (shared across the cluster) or single-node (enforced per process); required, never defaulted
DATAPRISM_SOURCES_CUSTOMER_BASE_URLExample only — declare DATAPRISM_SOURCES_<NAME>_BASE_URL (HTTPS) per configured source; at least one source, each with its own reviewed DataSourceAdapter bean, is required
DATAPRISM_SOURCES_CUSTOMER_TIMEOUTExample only — declare DATAPRISM_SOURCES_<NAME>_TIMEOUT (positive duration) per configured source; required alongside its base URL
