- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 100 (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`: 11 of 11 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 3,042 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 135 tool changes in 30 days
- fail `stability.rug_pull`: 44 tools kept their name but changed most of their description in 30 days; review before trusting them

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: dependencies not resolved yet

- tools: 11, about 3,042 tokens to load them all
- tool set hash: 9c008e1f18ce79ec6ad2da7d0b0151ee
- tools last changed: 2026-10-20T03:11:47.557Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.hydracept/hydracept.svg)](https://protogrid.dev/servers/com.hydracept/hydracept)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-20 `hydracept_status` removed
  - Check workspace/session readiness and common setup errors. Does not execute capabilities or spend money. Hosted requires bearer (WORKSPACE_KEY_REQUIRED when missing); stdio checks local project binding. Not a substitute for hydracept_capabilities. Returns: Workspace/session readiness diagnostics for the authenticated principal. Errors: WORKSPACE_KEY_REQUIRED when bearer is missing on hosted MCP.
- 2026-10-20 `hydracept_jobs_find` added
  - Find a prior job in the bound project when you do not have its id. intent is recent, failed, or reusable. The list never includes prompt text. Use after context loss, for failure triage, or to recover a job to cancel. Requires bearer key. No charge. Read-only. Returns: Matching job summaries for the filter. Errors: WORKSPACE_KEY_REQUIRED, INVALID_ARGUMENT.
- 2026-10-20 `hydracept_cancel_job` added
  - Request cancellation of one job. Use only when the user explicitly asks to cancel the job itself; stopping a local polling loop is not a cancellation. Returns whether the request was accepted, whether the job is already terminal, and the next action. Never promise that upstream provider work stopped or that already-incurred cost is refunded. Safe to retry: a terminal job reports its terminal state. Requires bearer key. Returns: Cancellation outcome envelope with job status, terminal flag, and next action. Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND, INVALID_ARGUMENT.
- 2026-10-20 `hydracept_job_status` changed (description)
  - before: Read one job's current status. Use after hydracept_submit_job or hydracept_run with wait=false; use hydracept_get_receipt after success. hydracept_job_inspect (POST /mcp/full) and hydracept_jobs_find (POST /mcp/full) are on the full profile (/mcp/full). Requires bearer key. No charge. Returns: HydraceptJob status projection for the jobId. Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND.
  - after: Read one job's current status. Use after hydracept_submit_job or hydracept_run with wait=false; use hydracept_get_receipt after success. If the job id is unknown, use hydracept_jobs_find first. Requires bearer key. No charge. Returns: HydraceptJob status projection for the jobId. Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND.
- 2026-10-20 `hydracept_workspace_status` added
  - Check workspace/session authentication and readiness, plus common setup errors. Use when setup, auth, or project binding is in doubt; use hydracept_job_status for a specific execution. Does not execute capabilities or spend money. Hosted requires bearer (WORKSPACE_KEY_REQUIRED when missing); stdio checks local project binding. Not a substitute for hydracept_capabilities. Returns: Workspace/session authentication and readiness diagnostics for the authenticated principal. Errors: WORKSPACE_KEY_REQUIRED when bearer is missing on hosted MCP.
- 2026-10-14 `hydracept_download_artifact` changed (description, annotations)
  - before: Fetch artifact metadata (and SHA-256 on hosted MCP) for a succeeded job output. Stdio may also write bytes when output_path is set. Requires bearer key. No charge on hosted.
  - after: Fetch artifact metadata (and SHA-256 on hosted MCP) for a succeeded job output. Stdio may also write bytes when output_path is set. Requires bearer key. No charge on hosted. Returns: Artifact downloadUrl, mediaType, sha256 (hosted does not write local files). Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND, DIRECTORY_CAPABILITY_DENIED when policy blocks.
- 2026-10-14 `hydracept_get_receipt` changed (description, annotations)
  - before: Read billing and provenance for a finished job. Does not run capabilities or spend money. Use after terminal success; use hydracept_job_status while still running. Hosted MCP accepts job_id only. Requires bearer key. No charge.
  - after: Read billing and provenance for a finished job. Does not run capabilities or spend money. Use after terminal success; use hydracept_job_status while still running. Hosted MCP accepts job_id only. Requires bearer key. No charge. Returns: HydraceptReceipt JSON for a terminal job. Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND when job or receipt is missing.
- 2026-10-14 `hydracept_job_status` changed (description, annotations)
  - before: Read one job's current status. Use after hydracept_submit_job or hydracept_run with wait=false; use hydracept_get_receipt after success. hydracept_job_inspect (POST /mcp/full) and hydracept_jobs_find (POST /mcp/full) are on the full profile (/mcp/full). Requires bearer key. No charge.

Requires bearer key. No charge. Returns: HydraceptJob status projection for the jobId. Errors: WORKSPACE_KEY_REQUIRED, NOT_FOUND.
- 2026-10-14 `hydracept_submit_job` changed (description, annotations)
  - before: Start a capability job and return its id immediately (paid). Use when execution is required but this MCP call must not block — not for quotes or status checks. Prefer hydracept_run when waiting is acceptable. Poll with hydracept_job_status. Same billing as hydracept_run. Requires bearer key.
  - after: Start a capability job and return its id immediately (paid). Use when execution is required but this MCP call must not block — not for quotes or status checks. Prefer hydracept_run when waiting is acceptable. Poll with hydracept_job_status. Same billing as hydracept_run. Requires bearer key. Returns: Job admission envelope with jobId and nextAction poll. Errors: WORKSPACE_KEY_REQUIRED, INVALID_ARGUMENT, FundingRequired, EXECUTION_FAILED.
- 2026-10-14 `hydracept_run` changed (description, annotations)
  - before: Run a capability (paid). Use when the user wants execution — not for quotes (hydracept_quote_capability), status (hydracept_job_status), or receipts (hydracept_get_receipt). Default wait=true waits until the job finishes; use hydracept_submit_job when this call must return immediately. Picks invoke vs durable job from the capability descriptor. Requires bearer key. Settles at actual provider cost plus any managed service fee; no per-call minimum. May create jobs, artifacts, and provider usage.

Default wait=true waits until the job finishes; use hydracept_submit_job when this call must return immediately. Picks invoke vs durable job from the capability descriptor. Requires bearer key. Settles at actual provider cost plus any managed service fee; no per-call minimum. May create jobs, artifacts, and provider usage. Returns: Terminal hydracept.run-result.v1 or job envelope when wait=false. Errors: WORKSPACE_KEY_REQUIRED, INVALID_ARGUMENT, FundingRequired, EXECUTION_FAILED, job timeout when wait exhausts.

Errors: NOT_FOUND for unknown key; INVALID_ARGUMENT for conflicting query parameters.
- `hydracept_download_artifact`: Fetch artifact metadata (and SHA-256 on hosted MCP) for a succeeded job output. Stdio may also write bytes when output_path is set. Requires bearer key.
