## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 681 tokens (~227/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 5 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## Install

### How do I install the RunBoth MCP server?

RunBoth is a hosted endpoint at https://runboth-agent-mgbxvs4loq-uc.a.run.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

First indexed and scored.

## MCP tools (3)

### `ask` (~240 tokens)

Ask runboth.dev a question in plain language and get the answer from its own pages, with sources. RunBoth is a zero-dependency Python tool that finds out what a refactor actually changed by running the old and the new code on generated inputs and comparing seven behaviour channels, rather than reading the diff. Covers: detecting behavioural change from a Python refactor; differential execution and the seven channels it compares; installing RunBoth and running it as a commit hook or GitHub Action; what a CHANGED, NO CHANGE or ABSTAINED verdict means; how RunBoth was red-teamed and where its limits are. For example: How do I find out what my Python refactor actually changed in behaviour? Answers come back as ranked pages from runboth.dev with a URL, a score and a one-line reason each.

Input parameters:

- `generate_mode` (string): The type of response to generate
- `query` (string, required): The question, in plain language. For example: How do I find out what my Python refactor actually changed in behaviour?
- `site` (array): Optional list of sites to search. If not provided, searches all configured sites

### `list_sites` (~20 tokens)

List the sites this endpoint answers for (runboth.dev).

### `trust_lookup` (~107 tokens)

Look up what AI agents recorded after calling a website or an MCP endpoint: which capability they used, whether it worked, how long it took, and what they learned. Read-only, no key. Use it before you trust an endpoint you have never called, including this one.

Input parameters:

- `target` (string, required): A domain or endpoint URL, for example runboth.dev or https://host/mcp
- `top_k` (integer): How many records to return, 1 to 25

## Common questions

### What is the RunBoth MCP server?

RunBoth is an MCP server listed in the public MCP registry as dev.runboth/agent. Ask runboth.dev in plain language: what RunBoth does, how to install it, and its limits. This page covers its hosted endpoint (https://runboth-agent-mgbxvs4loq-uc.a.run.app/mcp).

### Is the RunBoth MCP server safe to use?

RunBoth scores 59 out of 100 on VerifyMCP. 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 RunBoth MCP server expose?

RunBoth exposes 3 tools: ask, list_sites, trust_lookup. Their descriptions and schemas cost roughly 367 tokens of context every time the server is loaded.

### Does the RunBoth MCP server require authentication?

No. We connected to RunBoth without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the RunBoth MCP server still maintained?

RunBoth is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
