What it does

Wraps a private internal-knowledge API: search and retrieve. The category is interesting because it targets the knowledge that lives in people rather than wikis, which is exactly what agents usually cannot reach. Ask who can see what before enabling it on a shared account.

Install

Terminal

npx -y @tacitai/mcp-server

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

mcp.json

{
  "mcpServers": {
    "tacitai": {
      "command": "npx",
      "args": [
        "-y",
        "@tacitai/mcp-server"
      ]
    }
  }
}

Use it for

Searching internal knowledge that never made it into docs

Skip it if

Anything requiring a citation you can show a customer

When to use it

Reach for this when the task needs knowledge inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

Other TypeScript servers

Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
