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 Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified

Stability & Change Management77
- Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- 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

- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

Background: How many MCP packages publish verified provenance →
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 →
inspect_local_runtimes ~106
Use this when you have an explicit local PID, host binding, or bounded current-user inventory and need observation Proofs. Do not use it to claim an approved artifact match; use verify_local_runtime with an expectation for that decision.
| Name | Type | Req | Description |
|---|---|---|---|
| all | boolean | – | inspect a bounded current-user inventory |
| binding_id | string | – | optional host binding identifier |
| limit | integer | – | inventory limit when all is true |
| pid | integer | – | positive local process identifier |
| Name | Type | Req | Description |
|---|---|---|---|
| proofs | null|array | yes | – |
No examples provided.
list_local_runtime_candidates ~93
Use this when the local PID or host binding is unknown and you need bounded, safe candidate summaries without artifact hashing. Do not use it to claim that a runtime matches an approved artifact or to request an exhaustive system inventory.
| Name | Type | Req | Description |
|---|---|---|---|
| binding_id | string | – | optional host binding identifier |
| host_id | string | – | optional host profile identifier |
| limit | integer | – | maximum number of current-user processes to inspect |
| Name | Type | Req | Description |
|---|---|---|---|
| candidates | null|array | yes | – |
No examples provided.
verify_local_runtime ~129
Use this when you need to verify an explicit local PID or host binding against one declared local artifact expectation. Do not use it without an expectation, for remote processes, or to modify, stop, repair, or upgrade a runtime.
| Name | Type | Req | Description |
|---|---|---|---|
| binding_id | string | – | optional host binding identifier |
| expectation | null|object | – | inline expectation with absolute or home-relative roots |
| expectation_path | string | – | local expectation JSON file |
| known_prior_digests | null|array | – | directly known prior artifact SHA-256 values |

How do I install the Agent Runtime Proof MCP server?
Agent Runtime Proof ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

Download bundleThe MCP registry declares no SHA-256 for this bundle, so there is no published digest to check it against. Open it with an MCPB-capable host such as Claude Desktop.
What is the Agent Runtime Proof MCP server?
Agent Runtime Proof is an MCP server listed in the public MCP registry as io.github.fantasyce/agent-runtime-proof. Verify whether a local Agent or MCP runtime matches an approved artifact. This page covers its MCPB bundle (https://github.com/fantasyce/agent-runtime-proof/releases/download/v1.1.0/agent-runtime-proof_1.1.0.mcpb).
Is the Agent Runtime Proof MCP server safe to use?
Agent Runtime Proof scores 61 out of 100 on VerifyMCP. 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 Agent Runtime Proof MCP server expose?
Agent Runtime Proof exposes 3 tools: inspect_local_runtimes, list_local_runtime_candidates, verify_local_runtime. Their descriptions and schemas cost roughly 328 tokens of context every time the server is loaded.
What licence is the Agent Runtime Proof MCP server under?
Agent Runtime Proof declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
