How this service works
Signed drift history for one MCP server: pins over time, every detected drift event, and a current verdict (stable, changed, or poisoning-suspect). $0.05 USDC per report.
Output
Returns a structured drift report detailing all differences between the MCP server's current manifest and an expected or previous baseline — including added, removed, and modified tools, resources, prompts, or metadata fields, along with a summary of the overall drift severity.
Example use cases
Compliance audit of MCP server
“Run a full manifest drift report on our production MCP server at https://mcp.mycompany.com and tell me every tool, resource, or endpoint that has been added, removed, or modified since the last approved baseline.”
Post-deploy manifest verification
“We just deployed a new version of our MCP server — can you generate a drift report comparing the current manifest at https://staging.mcp.io to what we expected, so I can catch any accidental changes before it goes live?”
Ongoing manifest drift monitoring
“Pull a drift report for my MCP server manifest at https://internal-mcp.dev and summarize any discrepancies I should be aware of — I'm trying to keep the manifest stable week over week.”
Technical details
Endpoint
POSThttps://attester.dev/v2/mcp/reportWhen to prefer
Prefer this endpoint over the sibling 'MCP Manifest Drift Check' when you need a full, detailed drift report rather than a simple pass/fail check — ideal for audits, compliance reviews, post-deployment verification, or building a change log of MCP manifest evolution over time.
Side effects
- Unreachable MCP server URL results in a connection error
- Invalid or unparseable manifest returns a parsing failure response
- No baseline provided may result in an empty or trivial diff
- Rate limiting or payment failure at $0.05 USDC per call blocks the request
- Malformed request body returns a 400 bad request error
