Common questions

Is Claims MCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 days ago, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

claims-mcp

A small memory for agents that treats what it knows as claims that age. You assert a claim about an entity ("acme is priority #1", "the launch is on track"), each claim decays on a half-life set by how volatile it is, and the server tells you which claims have gone stale and which contradict each other.

It is a stdio MCP server plus a CLI over one local SQLite file. No network, no accounts.

Runtime: Bun. v0 uses bun:sqlite, so it runs on Bun ≥ 1.1, not plain Node. A Node build (node:sqlite) is a possible follow-up.

Model

Field	Meaning
`entity`	What the claim is about (free text key).
`kind`	`priority` (may carry `assertedRank`), `status`, `fact`, `relationship`.
`volatility`	`stable` (half-life 365d), `slow` (30d), `volatile` (7d).
`confidence`	0..1 at last confirmation. Effective confidence halves every half-life since `lastConfirmed`, floored at 0.05.
`state`	`active`, `stale`, `contradicted`, `retired`. Only `active` claims are checked.

A claim's identity is (entity, kind, claim): asserting it again updates it rather than duplicating.

MCP tools

Tool	Does
`claim_add`	Assert or update a claim.
`claim_search`	Case-insensitive substring search over claim text and entity.
`claim_confirm`	Re-confirm now: resets decay, reactivates, optionally sets confidence.
`claim_retract`	Retire a claim.
`claims_contradictions`	Conflicts among active claims: `duplicate-rank` (two entities claim the same priority rank), `status-conflict` (several active status claims for one entity). Pass `observed` weekly ranks to also get `rank-drop`: an asserted-priority entity that every signal ranks worse than `rank + 2` for 3 valid periods.
`claims_decayed`	Active claims past a staleness threshold (default 0.5), stalest first.

Resource: claims://all (every claim as JSON).

observed is { "signals": [{ " ": [rank_now, rank_1_period_ago, ...] }, ...], "validPeriods": [true, ...] }. You supply the observations (commit counts, time spent, anything you can rank); the server does not collect them.

Use

bun install

Add to an MCP client (Claude Code shown):

claude mcp add claims -- bun /path/to/claims-mcp/src/mcp.ts

The database lives at ~/.claims-mcp/claims.db; override with --db or CLAIMS_MCP_DB.

CLI:

bun src/cli.ts add acme priority slow 0.8 "acme comes first" --rank 1

bun src/cli.ts search comes bun src/cli.ts stale 0.5 bun src/cli.ts contradictions bun src/cli.ts confirm bun src/cli.ts retract

Development

bun test          # 19 tests, synthetic claims only

bun run typecheck bun run audit # publish gate: home paths, private names, secret patterns

Set AUDIT_TERMS="name1|name2" to add your own private names to the audit.

Provenance

Not a straight extraction. The decay curve and the rank-drop rule are ported from a personal agent memory (rank-drop now takes caller-supplied observations); the duplicate-rank and status-conflict rules are new claim-vs-claim logic written for this package. It shares no code, data or storage with the original.
