Claude Code: deny. ### `hydracept_cancel_job` - The name "hydracept_cancel_job" says "cancel": a word for removing or ending something. - The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Changes things (2) Creates or changes something that can be changed back. Claude Code: ask. ### `hydracept_run` - The name "hydracept_run" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. 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. ``` ### `hydracept_submit_job` - The name "hydracept_submit_job" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (8) Looks things up and changes nothing. Claude Code: allow. ### `hydracept_capabilities` - The description's first verb is "browse": a word for reading. Description, as the server wrote it: ```untrusted-server-text Browse or fetch capability descriptors (keys, modes, schemas). Use hydracept_resolve_capability when routing from intent alone. List/resolve is keyless; a bearer key may add project-scoped fields. No charge. Read-only. Returns: Capability list or single CapabilityDescriptor when key is set. Errors: NOT_FOUND for unknown key; INVALID_ARGUMENT for conflicting query parameters. ``` ### `hydracept_download_artifact` - The description's first verb is "fetch": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `hydracept_get_receipt` - The name "hydracept_get_receipt" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `hydracept_job_status` - The name "hydracept_job_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `hydracept_jobs_find` - The name "hydracept_jobs_find" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `hydracept_quote_capability` - The description's first verb is "preview": a word for reading. Description, as the server wrote it: ```untrusted-server-text Preview what a run would cost — does not execute, create a job, or charge the wallet. Use before spending when the user asks about price; use hydracept_run or hydracept_submit_job only to execute. Not the same as request_capability_quote (POST /mcp/full) on the full profile (human-paid capability commission). Requires bearer API key. No charge for the quote itself. Returns: Quote envelope with customerTotal and currency (no wallet charge). Errors: WORKSPACE_KEY_REQUIRED, INVALID_ARGUMENT, NOT_FOUND, FundingRequired when quote cannot be priced. ``` ### `hydracept_resolve_capability` - The name "hydracept_resolve_capability" says "resolve": a word for reading. Description, as the server wrote it: ```untrusted-server-text Match the user's goal to a capability key using natural language. Use when the key is unknown; use hydracept_capabilities when you already have a key or need the catalog. Keyless. No charge. Read-only. Returns: CapabilityResolutionResponse with ranked keys and rationale. Errors: INVALID_ARGUMENT when intent is empty; UNAUTHORIZED when bearer is invalid. ``` ### `hydracept_workspace_status` - The name "hydracept_workspace_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `hydracept`: ```json { "permissions": { "allow": [ "mcp__hydracept__hydracept_workspace_status", "mcp__hydracept__hydracept_capabilities", "mcp__hydracept__hydracept_resolve_capability", "mcp__hydracept__hydracept_quote_capability", "mcp__hydracept__hydracept_job_status", "mcp__hydracept__hydracept_get_receipt", "mcp__hydracept__hydracept_download_artifact", "mcp__hydracept__hydracept_jobs_find" ], "ask": [ "mcp__hydracept__hydracept_run", "mcp__hydracept__hydracept_submit_job" ], "deny": [ "mcp__hydracept__hydracept_cancel_job" ] } } ```
