## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 5 of 5 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: check_grade (destructiveHint, idempotentHint); get_capability (destructiveHint, idempotentHint); plan_route (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 883 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 883 tokens to load them all
- tool set hash: 6013eae21e646e4d0126bc17ee61e5a2
- tools last changed: 2026-09-27T08:47:08.081Z
- badge: [![protogrid quality](https://protogrid.dev/badge/xyz.teppi/teppi.svg)](https://protogrid.dev/servers/xyz.teppi/teppi)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-27 `check_exposure` added
  - Look up every paid endpoint your agents call in one go, added up by the address each one pays: which are unknown to the record, which took money and returned nothing, which list what they do not serve, and how much monthly spend sits on each. Unknown is reported as unknown, never as bad.
- 2026-09-27 `check_grade` changed (inputSchema)

## Tools (5)

- `check_exposure`: Look up every paid endpoint your agents call in one go, added up by the address each one pays: which are unknown to the record, which took money and returned nothing, which list what they do not serve, and how much monthly spend sits on each. Unknown is reported as unknown, never as bad.
- `check_grade`: Return what has been verified about an x402 endpoint or its url: whether it answers, what it charges, and whether that price has moved. Answers unrated rather than guessing when the evidence is thin. Works for endpoints Teppi does not operate, and a url never seen is put in line for a free handshake, so ask again in an hour.
- `get_capability`: Full detail for one capability: schemas, pricing, networks, the seller behind it, and every observation recorded against it.
- `plan_route`: Turn a goal and a budget into an ordered list of paid endpoints that could reach it, with a cost estimate and what has been verified about each step. Moves no money and buys nothing: it returns the plan for you to run yourself.
- `search_capabilities`: Search paid agent capabilities by task description. Returns the price, the input and output schemas, the networks each one settles on, and what has been verified about it. Sort by verified to put the ones with the most evidence behind them first. Use before paying an x402 endpoint you have not used.
