About tctc-mcp
tctc-mcp is an MCP server published by the GitHub account kofujimura. ERC-7303 token-controlled roles for AI agents: grant, check, and revoke permissions on-chain
It runs on your own machine: your AI client starts it from the npm package tctc-mcp at version 0.3.3.
It asks for one secret: TCTC_ADMIN_PRIVATE_KEY. Give it a key with the least access that still works.
Version 0.3.3 was published on 20 July 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
TCTC_ADMIN_PRIVATE_KEY | No | Yes | Issuer key enabling grant_role/revoke_role (admin mode). Omit for read-only mode: state-changing tools are then not even registered |
