Builds without SQLite FTS5 use a complete token-based Python fallback with lower ranking performance.\n- **Dense Semantic Vector Search (FastEmbed ONNX):** For fuzzy conceptual queries (*\"Where did the DB connection pool fail?\"* or *\"Why did authentication fail?\"*).\n- **Unified Diff Structural Mapping:** Automatically detects git diffs and PR diffs (`gh pr diff`, `gi…","publisher":null,"homepage":"https://github.com/k-rister/ephemeral-buffer-mcp","repository":"https://github.com/k-rister/ephemeral-buffer-mcp","version":"0.3.1","license":"Apache License\n                                   Version 2.0, …","protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:ephemeral-buffer-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":"code.generation","name":"Code Generation","confidence":0.917,"provenance":"derived"},{"slug":"data.vector-search","name":"Vector Search","confidence":0.825,"provenance":"derived"},{"slug":"dev.terminal","name":"Terminal & Shell","confidence":0.825,"provenance":"derived"},{"slug":"dev.version-control","name":"Version Control","confidence":0.745,"provenance":"derived"}],"categories":["code","data","dev"],"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":"ephemeral-buffer-mcp","registry":"pypi","observedAt":"2026-09-15T14:26:52.666Z","publishedAt":"2026-09-13T16:39:34.841198Z","latestVersion":"0.3.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"ephemeral-buffer-mcp","url":"https://pypi.org/project/ephemeral-buffer-mcp/","firstSeenAt":"2026-09-09T15:21:38.253Z","fetchedAt":"2026-09-15T14:24:45.122Z","normalizedAt":"2026-09-15T14:24:45.122Z"}]},"firstSeenAt":"2026-09-09T15:21:38.253Z","updatedAt":"2026-09-15T14:26:52.666Z"}
