    Server tool list (9)

    Raw names from tools/list. Only developers need these.

    hydracept_statusCheck 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.
    hydracept_capabilitiesBrowse 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_resolve_capabilityMatch 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_quote_capabilityPreview 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_runRun 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_jobStart 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.
    hydracept_job_statusRead 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.
    hydracept_get_receiptRead 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_download_artifactFetch 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.
