Couchbase Model Context Protocol Server to interact with Couchbase clusters

Trust verdict · v1 advisory · method

NOT YET SCREENEDno verdict on file

Verdict 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.

Environment variables

CB_CONNECTION_STRING

Couchbase connection string. Required for connecting to the cluster.

CB_USERNAME

Couchbase database username. Required for basic authentication.

CB_PASSWORD

secret

Couchbase database password. Required for basic authentication.

CB_CA_CERT_PATH

Couchbase CA certificate path. Required for TLS authentication in non Capella clusters.

CB_CLIENT_CERT_PATH

Couchbase client certificate path. Required for mTLS authentication.

CB_CLIENT_KEY_PATH

Couchbase client key path. Required for mTLS authentication.

CB_MCP_READ_ONLY_MODE

Couchbase read only mode. Set to true to allow disable write operations across both KV and query. KV write tools are not loaded and SQL++ queries that modify data are blocked. Set to false to allow data modification queries and tools.

CB_MCP_READ_ONLY_QUERY_MODE

[Deprecated] Couchbase read only query mode. Set to true to allow only read-only queries. Set to false to allow data modification queries. Use CB_MCP_READ_ONLY_MODE instead.

CB_MCP_TRANSPORT

Transport mode for the server (stdio, http or sse). Default is stdio

CB_MCP_HOST

Host to run the MCP server on (default: 127.0.0.1). Used only for HTTP and SSE transport modes.

CB_MCP_PORT

Port to run the MCP server on (default: 8000). Used only for HTTP and SSE transport modes.

CB_MCP_DISABLED_TOOLS

Tools to disable. Accepts comma-separated tool names (e.g., 'tool_1,tool_2') or a file path containing one tool name per line.

CB_MCP_CONFIRMATION_REQUIRED_TOOLS

Comma-separated tool names that require user confirmation before execution. Also accepts a file path containing one tool name per line. Requires the MCP client to support elicitation.

CB_CONNECTION_STRING

Couchbase connection string. Required for connecting to the cluster.

CB_USERNAME

Couchbase database username. Required for basic authentication.

CB_PASSWORD

secret

Couchbase database password. Required for basic authentication.

Verdict API

curl -s mcpindex.ai/api/v1/trust/server/io-github-couchbase-ecosystem-mcp-server-couchbase

Free-tier verdict as JSON: decision + dimensions + severity. Call it from your agent before it invokes a tool it just discovered.

Details

version: v0.8.0
category: Other
quality: 80 / 100
operator: Couchbase-Ecosystem

Provenance

Verdict history is anchored to Bitcoin via OpenTimestamps. The free tier returns the current verdict only; the anchored record is served on the authenticated tier.
