MCP server.\n\n---\n\n## ⚠️ No Guarantees\n\nThis is **not** a PRNG. This is **not** a test data framework with schema validation. This is a footgun with good trigger discipline expected of the operator.\n\n- Output is **plausible**, not **correct**\n- Output is **nondeterministic** — same schema, different result every time\n- Output is **not validated** — if the model returns garbage, you get garbage\n- Output is **not uniform** — LLMs have opinions about what \"random\" looks like\n\n**Good for:** seeding dev DBs, one-off REPL sessions, agentic pipelines that need typed data fast, anywhere plausible beats uniform.\n\n**Not for:** cryptography, reproducibility, performance-sensitive paths, production data.\n\n---\n\n## Install\n\n```bash\npip install grievous-mcp\n```\n\nSet your API key:\n\n```bash\nexport ANTHROPIC_API_KEY=sk-ant-...\n```\n\n---\n\n## Typical Usage\n\n### From Python\n\n```python\nfrom grievous.backend import generate\n\n# Single object — natural language schema\nuser = generate(\"a User with name, age, email, and city\")\n# {\"name\": \"Priya Nair\", \"age\": 34, \"email\": \"priya.nair@example.com\", \"city\": \"Bangalore\"}\n\n# Batch\nproducts = generate(\"a Product with id, name, price_usd, and category\", count=5)\n# [{\"id\": 1, \"name\": \"Wireless Headphones\", ...}, ...]\n\n# JSON Schema works too\nimport json\nschema = json.dumps({\n    \"type\": \"object\",\n    \"properties\": {\n        \"transaction_id\": {\"type\": \"string\", \"format\": \"uuid\"},\n        \"amount_usd\":     {\"type\": \"number\"},\n        \"status\":         {\"type\": \"string\", \"enum\": [\"pending\", \"cleared\", \"failed\"]},\n    }\n})\ntxn = generate(schema)\n# {\"transaction_id\": \"a3f1...\", \"amount_usd\": 142.5, \"status\": \"cleared\"}\n\n# Freeform — anything the model can hallucinate\ntensor = generate(\"a 4x4 float32 matrix, values between -1 and 1\")\ntimestamp = generate(\"an ISO 8601 timestamp from sometime in 2019\")\nphone = gene…","publisher":null,"homepage":"https://github.com/darthcoder/grievous","repository":"https://github.com/darthcoder/grievous","version":"0.1.1","license":"MIT","protocols":["mcp"],"tags":["anthropic","hallucination","llm","mcp","test-data"],"pricing":null,"endpoints":[{"url":"pypi:grievous-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"automation.workflows","name":"Workflow Automation","confidence":0.768,"provenance":"derived"}],"categories":["automation"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"grievous-mcp","registry":"pypi","observedAt":"2026-10-28T02:26:45.271Z","publishedAt":"2026-04-27T09:17:30.991407Z","latestVersion":"0.1.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"grievous-mcp","url":"https://pypi.org/project/grievous-mcp/","firstSeenAt":"2026-09-09T16:24:58.468Z","fetchedAt":"2026-10-28T02:25:05.219Z","normalizedAt":"2026-10-28T02:25:05.219Z"}]},"firstSeenAt":"2026-09-09T16:24:58.468Z","updatedAt":"2026-10-28T02:26:45.271Z"}
