It runs on your own laptop: no account,\nno cloud service, no telemetry. Works with any MCP client that can launch a stdio server, such as\nClaude Code, Claude Desktop, Cursor, Zed or VS Code.\n\nThe agent gets five kinds of memory:\n\n| Kind | Holds | Fades (half-life) |\n|---|---|---|\n| `preference` | how you like things done (\"use uv, not pip\") | 180 days |\n| `procedural` | workflows that worked (\"release = tag, then `make release`\") | 365 days |\n| `fact` | durable facts not in the code or docs | 180 days |\n| `episodic` | what happened in a past task: goal, decisions, open items | 30 days |\n| `trace` | short-lived log of files/commands, for resuming work | 7 days, deleted after 30 |\n\nMemories you use get reinforced and stay. Unused ones fade and are archived: moved, never\nsilently deleted. Inferred memories stay *provisional* (hidden) until confirmed. A correction\n*supersedes* the old memory instead of contradicting it.\n\n## Install\n\nYou need [uv](https://docs.astral.sh/uv/). Then add the server to your client.\n\n**Claude Code**\n\n```bash\nclaude mcp add memory --scope user -- uvx halflife-mcp\n```\n\n**Claude Desktop** (Settings → Developer → Edit Config → `claude_desktop_config.json`), Cursor\n(`~/.cursor/mcp.json`) and most other clients use the same shape:\n\n```json\n{\n  \"mcpServers\": {\n    \"memory\": {\n      \"command\": \"uvx\",\n      \"args\": [\"halflife-mcp\"]\n    }\n  }\n}\n```\n\nIf the client can't find `uvx`, put its absolute path in `command` (`which uvx`).\n\n### Local HTTP mode\n\nFor clients that connect by URL instead of launching a command, run the server yourself:\n\n```bash\nuvx halflife-mcp serve --http  # http://127.0.0.1:8765/mcp\nclaude mcp add --transport http memory http://127.0.0.1:8765/mcp  # e.g. Claude Code\n```\n\nThere is no authentication, so it listens on loopback only: other machines can't reach it.\nRequests whose `Host` or `Origin` isn't local are rejected, which stops a web page from\ntalking to i…","publisher":null,"homepage":"https://github.com/Oleg67/halflife-mcp","repository":"https://github.com/Oleg67/halflife-mcp","version":"0.1.3","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:halflife-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"knowledge.memory","name":"Agent Memory","confidence":0.848,"provenance":"derived"}],"categories":["knowledge"],"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":"halflife-mcp","registry":"pypi","observedAt":"2026-11-05T21:26:42.624Z","publishedAt":"2026-11-05T00:17:54.511123Z","latestVersion":"0.1.3"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"halflife-mcp","url":"https://pypi.org/project/halflife-mcp/","firstSeenAt":"2026-10-18T16:28:55.986Z","fetchedAt":"2026-11-05T21:25:40.265Z","normalizedAt":"2026-11-05T21:25:40.265Z"}]},"firstSeenAt":"2026-10-18T16:28:55.986Z","updatedAt":"2026-11-05T21:26:42.624Z"}
