Proofable MCP

Proofable MCP

The trust harness for AI, in every MCP client.

Connect Proofable once, and your agents can use your profile, proofs, permissions, and protected tools in Cursor, Claude, Codex, VS Code, ChatGPT, and any other MCP client.

Start

Open Set up Proofable, choose your client, and finish sign-in. Then ask:

Show my Proofable profile and the proofs I can reuse.

For a specific requirement:

Check whether I already have the proof needed for this task. Reuse it if it qualifies; otherwise show me the next step.

Connect

Add https://mcp.proofable.me/mcp to any MCP client, or use a standard MCP configuration:

{
  "mcpServers": {
    "proofable": {
      "type": "http",
      "url": "https://mcp.proofable.me/mcp"
    }
  }
}

The installer writes the same connection for supported clients:

npx -y @proofable/sdk setup

Claude Code installs the server and the workflow skills together:

/plugin marketplace add proofable/mcp
/plugin install proofable-mcp@proofable

Keep one Proofable connection per client. A marketplace plugin plus a manual entry creates a duplicate.

What agents can do

Outcome	Tools
Load the signed-in profile and current context	proofable_context
Find supported checks and their required inputs	proofable_verifiers_catalog
Check whether a qualifying proof already exists	proofable_proofs_check
Reuse a current proof or get the next verification step	proofable_verify_or_guide
Create or refresh a proof	proofable_verify
Prepare and submit a check needing another signer	proofable_verify_prepare, proofable_verify_submit
Find and read proofs	proofable_proofs_get
Update proof metadata or add feedback	proofable_proofs_update
Check, create, and load agent permissions	proofable_agent_link, proofable_agent_create, proofable_agent_mount

Call proofable_context once after connecting. Proofable reuses current proofs before starting another verification and returns Passed, Action needed, or Blocked.

The MCP tool reference lists every tool with its inputs and result shapes.

Servers and automation

Create an access key under Account → Access keys, store it as PROOFABLE_ACCESS_KEY, and send it as a Bearer token. Keep access keys out of source code, browser bundles, and chat.

{
  "mcpServers": {
    "proofable": {
      "type": "http",
      "url": "https://mcp.proofable.me/mcp",
      "headers": {
        "Authorization": "Bearer ${PROOFABLE_ACCESS_KEY}"
      }
    }
  }
}

Examples

• Prompt injection test: hides AgentDojo attacks in a note your agent reads, runs the task under a scoped and a broad permission, and grades every run from its signed receipt.
• Guarded agent action: makes one permission decision before host code runs a tool.

Build with Proofable

Use the Proofable SDK for application code, verification gates, and the CLI. This package carries the MCP registry manifest, the host plugins, and the workflow skills; the server runs at https://mcp.proofable.me/mcp.
