This reduces update time from minutes to seconds.\n\n```bash\n# Update repos and incrementally re-index (fast!)\nethereum-mcp update\n\n# Incremental index (default behavior)\nethereum-mcp index\n\n# Preview what would change without indexing\nethereum-mcp index --dry-run\n\n# Force full rebuild\nethereum-mcp index --full\n```\n\n**How it works:**\n1.…","publisher":{"name":"be.nvy","url":null},"homepage":"https://github.com/be-nvy/ethereum-mcp#readme","repository":"https://github.com/be-nvy/ethereum-mcp/blob/main/CHANGELOG.md","version":"0.3.1","license":null,"protocols":["mcp"],"tags":["consensus","eip","embeddings","ethereum","llm","mcp","model-context-protocol","rag","search"],"pricing":null,"endpoints":[{"url":"pypi:eth-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","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"data.vector-search","name":"Vector Search","confidence":1,"provenance":"declared"},{"slug":"finance.markets","name":"Markets & Trading","confidence":1,"provenance":"declared"},{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":0.768,"provenance":"derived"}],"categories":["data","dev","finance"],"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":"eth-mcp","registry":"pypi","observedAt":"2026-09-15T14:26:56.823Z","publishedAt":"2026-02-12T15:41:24.673473Z","latestVersion":"0.3.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"eth-mcp","url":"https://pypi.org/project/eth-mcp/","firstSeenAt":"2026-09-09T15:21:51.149Z","fetchedAt":"2026-09-15T14:24:58.397Z","normalizedAt":"2026-09-15T14:24:58.397Z"}]},"firstSeenAt":"2026-09-09T15:21:51.149Z","updatedAt":"2026-09-15T14:26:56.823Z"}
