mcpindex features and specs

Install once, rides your agent
One config-wire in Claude Desktop, Claude Code, Cursor, Gemini CLI, Cline, or Zed. The gate sits in your agent’s MCP session. No credentials; the contract-diff runs locally and the default build egresses nothing. The optional cloud tier-1 lookup, held off by default, sends only a contract hash-never tokens or call data.
Pins each tool on first sight
On first sight, the gate records the tool’s contract-name, params, constraints, annotations, schemas-and persists it across restarts. TOFU: the baseline is what you saw.
HOLDs the call when the contract changes
On every later call, the gate diffs the live contract against your pin. Silent required-param adds, narrowed constraints, or destructive flips HOLD the call and name the ChangeKind.
You review, re-pin, or validate
A held call is a decision: read the diff, re-pin the new contract, or send it back. Benign added-optional proceeds silently. The verdict is “this changed,” never “this is unsafe.”
