Overview

Across Protocol runs a hosted MCP server (mcp.across.to/mcp) that exposes full-text search over Across documentation, supported-chain lookups, real-time bridge fee data, and code samples. A self-hostable version was published at github.com/across-protocol/mcp-server-across; that repository returned 404 on 2026-09-26, so only the hosted endpoint is listed. An agent builder plugs it in to give an agent live cross-chain bridging context and fee data from Across without maintaining its own docs/fee cache.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

A remote server: your client connects to the project's endpoint. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

Tool inventory — 14 tools, probed live 2026-10-15

  • search_across_docs — Full-text search across the Across Protocol documentation. Use for any conceptual or how-to question about Across.
  • get_page — Get the full content of a specific Across documentation page. Accepts a path like '/reference/api-reference' or a keyword match. Prefer reading the `across://docs/...` resource directly when the path
  • get_code_examples — Get code examples from Across docs. Filter by topic like 'sdk', 'swap', 'deposit', 'viem', 'ethers'.
  • recrawl_docs — Kick off a background re-crawl of all Across documentation pages. Returns immediately; the index updates when the crawl completes.
  • get_supported_chains — List all chains supported by Across with their chain IDs, fetched live from the Across API.
  • get_api_reference — Get the Across REST API endpoint catalog. Pass an `endpoint` to filter; leave empty to list all.
  • get_suggested_fees — Live quote of bridge fees for a single-token transfer between two Across-supported chains.
  • get_swap_quote — Build a crosschain swap on Across. Returns the expected output, fees, and ready-to-sign calldata (`approvalTxns` + deposit `tx`). The client/user signs and broadcasts.
  • track_deposit — Look up the lifecycle status of an Across deposit by origin-chain tx hash or deposit ID.
  • list_deposits — Return recent Across deposits for a given depositor address.
  • get_available_routes — Discover supported (origin, destination, token) routes. All filters are optional; omit to list every route.
  • get_limits — Get the min/max transferrable amount for a given token between two chains.
  • swap_with_wallet — Open an interactive crosschain-swap view in the conversation. Fetches a live Across quote and renders a UI where the user verifies details, connects their wallet, and signs the deposit themselves. Use
  • track_deposit_app — Internal: deposit-status lookup used by the swap UI to poll fill progress.

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
