MCP server for autonomous AI agent trust — cryptographic provenance (Chain of Consciousness with Bitcoin OpenTimestamps), decentralized reputation (Agent Rating Protocol with bilateral blind evaluation). Part of the 7-protocol Agent Trust Stack.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"agent-trust-stack-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# Agent Trust Stack MCP Server MCP (Model Context Protocol) server exposing the **Agent Trust Stack** tools so any MCP-compatible AI agent can use them natively. Provides **Chain of Consciousness** (CoC) provenance logging and **Agent Rating Protocol** (ARP) reputation scoring — the two operational protocols from the [7-protocol Agent Trust Stack](https://vibeagentmaking.com). ## Tools | Tool | Description | |------|-------------| | `coc_init` | Initialize a new cryptographic hash chain (genesis block) | | `coc_add` | Append an entry — learn, decide, create, error, note, milestone, session_start/end | | `coc_verify` | Verify chain integrity (hash linkage, sequence, completeness) | | `coc_status` | Get chain stats (length, agents, time span, event types) | | `coc_tail` | Get the last N entries | | `coc_anchor` | Submit chain hash for external timestamping (OTS + RFC 3161 TSA) | | `arp_rate` | Submit a bilateral blind rating for another agent | | `arp_check` | Check an agent's reputation score | | `trust_stack_info` | Get info about all 7 protocols with whitepaper links | | `verify_agent_identity` | Verify an agent's identity via Agent Card URL | | `get_trust_evidence` | Get combined trust evidence (CoC + ARP) for an agent | ## Resources | URI | Description | |-----|-------------| | `trust-stack://protocols` | Overview of all 7 protocols with links | | `trust-stack://installation` | Installation instructions | ## Installation ```bash pip install agent-trust-stack-mcp ``` For proper OpenTimestamps .ots file format (optional): ```bash pip install agent-trust-stack-mcp[ots] ``` ## Configuration Add to your MCP client config (Claude Code, Cursor, etc.): ```json { "mcpServers": { "agent-trust-stack": { "command": "agent-trust-stack-mcp", "args": [] } } } ``` ### Environment Variables | Variable | Default | Description | |----------|---------|-------------| | `COC_CHAIN_DIR` | `./chain` | Directory for chain files | | `ARP_RATINGS_DIR`…
