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 →

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.

MCP tools · 14 exposed · ~1,300 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 →

Tool Tokens
find_symbol ~105

Where is a symbol defined (best match first), and with refs=true where it is used. Returns {"matches": [...], "remaining", "next_offset"?}; results are paged, never cut silently.

NameTypeReqDescription
namestringyesFunction, class or type name, e.g. "Cart".
offsetinteger–Skip this many results; use next_offset from the last call.
refsboolean–Also list call sites and uses (source before tests).

Structured output declared, but exposes no named fields.

No examples provided.

memory_search ~128

Search past Claude Code, Codex and OpenCode sessions, best match first. New sessions are indexed first. Returns {"hits": [{"agent", "session", "project", "ts", "role", "snippet"}], "remaining", "next_offset"?}.

NameTypeReqDescription
budget_charsinteger–Max characters of snippets returned.
offsetinteger–Skip this many hits; use next_offset from the last call.
querystringyesWords to look for, e.g. "stripe webhook signature".
this_project_onlyboolean–Only sessions that ran in this project.

Structured output declared, but exposes no named fields.

No examples provided.

proof_check ~91

Mark one requirement as verified, with concrete evidence (a command and its result, or file:line). Returns the updated requirement.

NameTypeReqDescription
evidencestringyesWhat you ran or saw, e.g. "pytest tests/test_cart.py::test_once passed" or "cart.py:14 caps at one use".
requirement_idintegeryesThe id from proof_requirements, e.g. 1.

Structured output declared, but exposes no named fields.

No examples provided.

proof_requirements ~79

Record what the user asked for as a checklist. Call this first. Duplicate items are ignored. Returns {"requirements": [{"id", "text", "done", "evidence"}]}.

NameTypeReqDescription
itemsarrayyesOne short, checkable item per user ask, e.g. ["discount applies once", "empty cart costs 0"].

Structured output declared, but exposes no named fields.

No examples provided.

proof_run_tests ~101

Run the project's tests and record the result as evidence. Returns {"exit", "passed", "seconds", "cmd", "output"} where output is a compact tail.

NameTypeReqDescription
commandstring–Optional override, e.g. "pytest -q tests/test_cart.py". Default: [proof].test_cmd or auto-detected.
phasestring–"before" your change (baseline) or "after" it (required by the gate).

Structured output declared, but exposes no named fields.

No examples provided.

proof_status ~34

Is the work proven? Returns {"proven", "missing": [what to do next], "requirements", "report"}.

Input schema present but exposes no named parameters.

Structured output declared, but exposes no named fields.

No examples provided.

read_file ~129

Read a project file. A repeat read of an unchanged file returns a one-line notice instead of the text; a changed file returns only the diff since your last read. Returns {"path", "content"}.

NameTypeReqDescription
endinteger–Last line, inclusive; 0 = end of file.
forceboolean–Return the full text even if you read it before (e.g. after compaction).
pathstringyesProject-relative path, e.g. "src/cart.py". Windows separators are accepted.
startinteger–First line, 1-based.

Structured output declared, but exposes no named fields.

No examples provided.

NameTypeReqDescription
output_idstringyesThe id printed by run_compact, e.g. "3f9a1c2b7d4e".

Structured output declared, but exposes no named fields.

No examples provided.

rewind_list ~68

List recent workspace snapshots, oldest first. One is taken after every edit or shell command. Returns {"steps": [{"step", "tool", "ts", "files", "n_files"}], "total"}.

NameTypeReqDescription
lastinteger–How many recent steps, e.g. 20.

Structured output declared, but exposes no named fields.

No examples provided.

rewind_to ~75

Restore project files to how they were after `step`. A safety snapshot is taken first, so calling rewind_to(safety_step) undoes this. Returns {"restored", "removed", "safety_step", "new_step"}.

NameTypeReqDescription
stepintegeryesA step number from rewind_list, e.g. 3.

Structured output declared, but exposes no named fields.

No examples provided.

run_compact ~94

Run a command and return output with failures, errors and file:line kept and noise dropped. Returns {"exit", "output"}; the output ends with an id for recall() when anything was cut.

NameTypeReqDescription
commandstringyesCommand line, run without a shell, e.g. "pytest -q" or "git log -n 20".
timeoutinteger–Seconds before the command is killed.

Structured output declared, but exposes no named fields.

No examples provided.

swarm ~193

Run small tasks on the configured helper model in parallel. Each answer is checked: citations (path:line) must exist; drafts must apply and pass the tests in a throwaway copy (never applied to your files). Failed answers are retried with the checker's notes, best-of-N, then escalated to the strong model if set. With no helper model configured, returns {"mode": "plan", "subagent_tasks": [...]} for your own subagents.

NameTypeReqDescription
tasksarrayyesEach: {"kind": "ask"|"summarize"|"draft_edit"|"grep", "prompt": str, "files": [paths], "symbols": [names]}. "symbols" narrows the context to those definitions. Tip: swarm_plan builds this list for yo…

Structured output declared, but exposes no named fields.

No examples provided.

work_state ~108

Common questions

What is the keelyard MCP server?

keelyard is an MCP server listed in the public MCP registry as io.github.akobirjontulqinovfuture/keelyard. Proof gate, undo and output trimming for Claude Code, Codex and OpenCode coding agents. This page covers its PyPI package (keelyard).

Is the keelyard MCP server safe to use?

keelyard scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 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 keelyard MCP server expose?

keelyard exposes 14 tools: proof_requirements, proof_check, proof_run_tests, proof_status, rewind_list, and 9 more. Their descriptions and schemas cost roughly 1,300 tokens of context every time the server is loaded.

Is the keelyard MCP server still maintained?

keelyard is still listed as active in the MCP registry. We last reached this channel on 5 November 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 keelyard MCP server under?

keelyard 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.
