Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
  • 8 of 75 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to anzar-ahsan-commits/api-shakedown). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 0 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability60
  • AI-judged instruction clarity (fair).Partial
  • Tool/resource definitions use about 393 tokens (~65/item across 6 items; 6 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
  • Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

MCP tools · 6 exposed · ~295 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

generate_harness ~123

Generate a ready-to-run chaos test harness for an OpenAPI spec into out_dir. offline=true skips the LLM (deterministic, seconds); otherwise this takes minutes on a local model, and review=false roughly halves that. Refuses a non-empty out_dir unless force=true (which overwrites only the harness's own files).

Common questions

What is the API Shakedown MCP server?

API Shakedown is an MCP server listed in the public MCP registry as io.github.anzar-ahsan-commits/api-shakedown. Turn an OpenAPI spec into WireMock stubs, contract tests and chaos scenarios, on local LLMs. This page covers its PyPI package (api-shakedown).

Is the API Shakedown MCP server safe to use?

API Shakedown scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 October 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the API Shakedown MCP server expose?

API Shakedown exposes 6 tools: doctor, inspect_spec, generate_harness, list_chaos_scenarios, activate_chaos, deactivate_chaos. Their descriptions and schemas cost roughly 295 tokens of context every time the server is loaded.

Is the API Shakedown MCP server still maintained?

API Shakedown is still listed as active in the MCP registry. We last reached this channel on 25 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the API Shakedown MCP server under?

API Shakedown declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
