# web3ctx ### The last mile before your agent signs.

## Five tools | tool | what it does | |---|---| | `web3_search` | ranked, version-scoped units β€” plus the human-validated recipe when the question earns one | | `web3_grep` | exact identifier lookup across the corpus | | `web3_fetch` | full bodies by stable selector, cursor paging for long content | | `web3_deps` | dependency closure, stepped by depth | | `web3_lookup` | typed records β€” deployment addresses, ABIs, EIPs β€” or an honest `NOT_FOUND` | ## A real answer **β€œhow do I bridge USDC with CCTP”** β€” one call to the authless endpoint, 2026-08-28: ```json { "intent": "lookup", "recipe": { "project_id": "cctp", "version": "2", "recipe_type": "usdc-bridge-send", "last_validated": "2026-08-07", "validated_by": "farseen (github: FarseenSh)", "receipts": { "validated_on": "2026-08-07", "validated_by": "farseen (github: FarseenSh)", "checks": [ "attest", "test" ], "chains_exercised": [ "base-sepolia", "arbitrum-sepolia" ], "on_chain": [ { "kind": "txHash", "hash": "0xd4b4e6395f52ad726dd6062e7a7ec47a2d3a7875d36f20fbb154cde756a3d0f5", "role": "approve", // … 207 more lines β€” the receipts, the // validated recipe body, and ten citations each pinned to a commit or an exact package version. ``` The whole response is 26,191 bytes (sha256 `bc58a9feba1f6309…`) and it publishes byte-for-byte: [`evidence/showcase/cctp-search.json`](https://github.com/FarseenSh/web3ctx/blob/HEAD/evidence/showcase/cctp-search.json). Diff it against your own call. ## Why this exists **It does not get fooled by a wrong premise.** Ten questions built on premises verified false before the run β€” an archived repo, a renamed package, a version that does not exist. web3ctx was deceived **0 of 10**; every other arm was deceived at least once (1–3 of 10). πŸ”΄ Our own `intent=integrate` row was deceived **once**, and it publishes here beside the other: a stray line in one recipe cited an archived repository. [The ten traps and every arm’s answer β†’](https://github.com/FarseenSh/web3ctx/blob/HEAD/evals.html) **Citations you can re-fetch.** Every unit carries `project@version` and a URL pinned to a 40-character commit: **142 of 144** across the audited payloads, against **~0** for every tool compared. [The audit protocol β†’](https://github.com/FarseenSh/web3ctx/blob/HEAD/evals.html) **When it does not know, it says so.** Asked about eight projects it does not index, it declines all eight and names what would resolve each one. Competitors answer most of them. ⚠ Zero confabulated rows anywhere, **including ours** β€” that column separates nobody, and it is reported rather than claimed as an advantage. [Abstention honesty β†’](https://github.com/FarseenSh/web3ctx/blob/HEAD/evals.html) **The recipes are the moat.** Each one was run by a human against live chains and ships with the transaction receipts, so anyone can check the claim by RPC rather than trusting the stamp. ## Freshness, stated honestly Every unit carries **`as_of`** β€” the committer date of the **commit we pinned** β€” and a citation that resolves to an immutable, re-fetchable reference. Rebuilds are **dated events**, stamped into `corpus_version` and visible on the coverage page along with when the index was last loaded. πŸ”΄ **No refresh cadence is claimed anywhere**, because we could not keep one. A 2020 date on an archived repository is not staleness β€” it is the newest thing upstream ever published. [Per-project dates and coverage β†’](https://github.com/FarseenSh/web3ctx/blob/HEAD/coverage.html) ## Quickstart ```bash claude mcp add --transport http web3ctx https://mcp.scarai.xyz/mcp ``` ```json { "mcpServers": { "web3ctx": { "type": "http", "url": "https://mcp.scarai.xyz/mcp" } } } ``` Cursor, Windsurf, Zed and any MCP client: add the same URL β€” `https://mcp.scarai.xyz/mcp` β€” as a remote HTTP server. No key, no signup β€” the free tier is the read path and always will be. ## How a question is answered [![The web3ctx serving path β€” interactive architecture map](https://github.com/FarseenSh/web3ctx/blob/HEAD/serving-path.png)](https://web3ctx.scarai.xyz/serving-path.html) **[Open the interactive map β†’](https://web3ctx.scarai.xyz/serving-path.html)** β€” hover any component, trace routes, play the three guided views. *Resolve entities β†’ bind or **ABSTAIN** the version from evidence β†’ filter by SQL predicate, rank with BM25 within β†’ budget-true payload, citations before bodies. Deterministic end to end β€” no model on the serving path.* ## The evidence This repository carries every measurement behind the claims above β€” including the experiments that failed, the gates we did not clear, and the corrections to things we published wrong. Competitor payload **bytes** are withheld by rule; their protocol, hashes and counts are all here, so any count can be re-run against the live tools. **[Read the evidence β†’](https://github.com/FarseenSh/web3ctx/blob/HEAD/evidence/README.md)** Β· [overview](https://github.com/FarseenSh/web3ctx/blob/HEAD/index.html) Β· [evals](https://github.com/FarseenSh/web3ctx/blob/HEAD/evals.html) Β· [coverage β€” is your stack in there?](https://github.com/FarseenSh/web3ctx/blob/HEAD/coverage.html) Β· [who runs it, and what it logs](https://github.com/FarseenSh/web3ctx/blob/HEAD/operator.html) Β· [architecture](https://github.com/FarseenSh/web3ctx/blob/HEAD/architecture.html) Licensed **MIT** (code and site) and **CC BY 4.0** (the evidence documents) β€” [why there are two](https://github.com/FarseenSh/web3ctx/blob/HEAD/LICENSES.md).
