Overview

Description from the maker (original English)

Hosted MCP for Hydracept: discover capabilities, run jobs, receipts, BYOK or managed billing.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: HYDRACEPT_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 11 things (tools) hydracept_workspace_status, hydracept_capabilities, hydracept_resolve_capability, hydracept_quote_capability …
  • You fill in yourself: HYDRACEPT_API_KEY, HYDRACEPT_MCP_TOOL_PROFILE, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "hydracept": {
      "command": "uvx",
      "args": [
        "hydracept",
        "mcp",
        "serve"
      ],
      "env": {
        "HYDRACEPT_API_KEY": "your-value",
        "HYDRACEPT_MCP_TOOL_PROFILE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http hydracept https://api.hydracept.com/mcp --header 'Authorization: Bearer {HYDRACEPT_API_KEY}'

Or run it on your computer

claude mcp add hydracept --env HYDRACEPT_API_KEY=your-value --env HYDRACEPT_MCP_TOOL_PROFILE=your-value -- uvx hydracept mcp serve

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "hydracept": {
      "url": "https://api.hydracept.com/mcp",
      "headers": {
        "Authorization": "Bearer {HYDRACEPT_API_KEY}"
      }
    }
  }
}

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • hydracept_workspace_status

    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 wh

  • hydracept_capabilities

    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

  • hydracept_resolve_capability

    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:

  • hydracept_quote_capability

    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 (huma

  • hydracept_run

    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 immedi

  • hydracept_submit_job

    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

  • hydracept_job_status

    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.

  • hydracept_cancel_job

    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 p

  • hydracept_get_receipt

    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. E

  • 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. No charge on hosted. Returns: Artifact downloadUrl, mediaType, sha256 (hosted does not write local files). Errors: WORKSPACE_KE

  • hydracept_jobs_find

    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 j

Common questions

Is Hydracept 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?

You need to fill in: HYDRACEPT_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.4) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Hydracept

Hydracept is an execution control plane for software and AI agents that need external capabilities—text, reasoning, image, audio, video, 3D, domains, and compute—through one API with discovery, quotes, durable jobs, artifacts, receipts, budgets, and BYOK. Games and media are common examples; a headline workflow is AI game assets from Cursor or Claude Code into Unity (workflow overview).

Pricing (summary): Free plan ($0/mo) for individuals; paid plans add capacity. BYOK at 0% Hydracept fee; managed inference is provider cost + 6% service fee (actual usage, no per-call minimum). Eligible durable text jobs can use deferred processing at 50% of standard token rates. Details: hydracept.com/pricing and Billing docs.

Install

SurfaceCommand
Python CLI & SDKpip install -U hydracept
TypeScriptnpm install @hydracept/sdk
.NETdotnet add package Hydracept.Client
Unity (UPM git)com.hydracept.unity via Git URL — see Unity integration (OpenUPM listing pending owner submit)

Public HTTP API: https://api.hydracept.com · OpenAPI: hydracept-v1.json · Agent context: GET https://api.hydracept.com/v1/agent-context

Bootstrap

pip install -U hydracept

python -m hydracept init --apply --yes --json python -m hydracept doctor

Studio (browser): app.hydracept.com/login. For CI or headless use, set HYDRACEPT_API_KEY and run the same init command with --ci when you need setup grants. Workspace files live under .hydracept/ — see Authentication.

Minimal example

One-shot image generation (composes init when the workspace can be bootstrapped):

python -m hydracept run image.generate.v1 --prompt "transparent 1024x1024 blue slime icon" --json

Python SDK (after init binds the workspace):

from hydracept.client import HydraceptClient

client = HydraceptClient.from_workspace() job = client.submit_capability_job( "image.generate.v1", { "input": {"prompt": "cute slime icon, flat game art"}, "execution": {"executionPreference": "automatic"}, "idempotencyKey": "demo-1", }, ) finished = client.wait_for_job(job["jobId"]) receipt = client.get_job_receipt(job["jobId"])

Discover capabilities live (do not hard-code keys from this README):

python -m hydracept capabilities find "generate an image"

curl -sS -H "Authorization: Bearer $HYDRACEPT_API_KEY" https://api.hydracept.com/v1/capabilities

More examples: public/examples/.

MCP (Cursor & Claude Code)

In a project checkout, stdio MCP is the default after init:

python -m hydracept init --apply --yes --json   # binds MCP to workspace secrets; reload MCP if prompted

python -m hydracept mcp serve # stdio server python -m hydracept agents install --auto # Cursor / Claude Code plugin + hooks

  • Plugin & install links: hydracept.com/plugin
  • Hosted MCP (no repo checkout): https://api.hydracept.com/mcp with bearer HYDRACEPT_API_KEY
  • MCP Registry name: com.hydracept/hydracept

Do not paste workspace API keys into IDE plugin config when stdio bind is available. Full agent guide: Coding Agents.
