Hydracept
Hosted MCP for Hydracept: discover capabilities, run jobs, receipts, BYOK or managed billing.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http hydracept 'https://api.hydracept.com/mcp' --header 'Authorization: <Authorization>'
{
"mcpServers": {
"hydracept": {
"type": "http",
"url": "https://api.hydracept.com/mcp",

"Authorization": "<Authorization>"
}
}
}
}

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
| Surface | Command |
|---|---|
| Python CLI & SDK | pip install -U hydracept |
| TypeScript | npm install @hydracept/sdk |
| .NET | dotnet 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/mcpwith bearerHYDRACEPT_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.
