Connect Canon (wallstreet.wiki) and your agent gets 13 tools, among them canon_batch, canon_changes, canon_cite. It answers at https://canon.wallstreet.wiki/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Finance canon lookup plus 30 deterministic formulas, each with a verifiable receipt.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
canon_batch | Run up to 50 computes in one call, for scenario grids and sensitivity tables. Each item returns its own receipt; the batch receipt id is sha256 over the sorted item receipt ids, so a whole table can be cited by one hash. Inputs: items |
canon_changes | Aggregated dated change events across every vertical, newest first. Poll this instead of re-crawling. Inputs: since |
canon_cite | Ready-to-paste citation strings (markdown, plain, apa, bibtex) for one entry, with the reviewed date. Use when writing a report that quotes the canon. Inputs: site, id, format |
canon_compute | Run one formula from the registry on validated inputs. Returns outputs, the convention used, citations, and a receipt whose id is sha256 over formula, version, canonical inputs and outputs. Invalid inputs return an explicit problem list and Inputs: formula, inputs |
canon_contract | Fetch one Kalshi (ticker) or Polymarket (slug or condition id) contract and return rules text, close time, resolution source and status in one shape. For a paid cross-venue identity check with a snapshot receipt, call GET /v1/contracts/comp Inputs: venue, id |
canon_describe_formula | Input schema with ranges and defaults, output names, stated convention, citations and test vectors for one formula. Inputs: formula |
canon_entity | Map a ticker (AAPL, BRK.B), a CIK, or a company name to one issuer id with every ticker and exchange, plus EDGAR filing locations. Use before joining prices, filings and news so identifiers line up; source is the SEC public ticker file. Inputs: q, limit |
canon_get_entry | Full definition and notes for one entry, by site and id (ids come from canon_search). Inputs: site, id |
canon_list_formulas | The deterministic formula registry: id, site, summary, input names and citations. Call canon_describe_formula for a schema. |
canon_search | Search defined terms and reference tables across all canon sites (options, fixed income, quants, PE, M&A, private credit, venture, hedge funds). Returns ranked hits with a citable url and the JSON source. Inputs: q, site, limit |
canon_sites | The sites in the .wiki finance canon with live entry counts and review dates. |
canon_thresholds | Reference table of the regulatory figures agents get wrong: 13F, 13D and 13G, Form 4, Form PF tiers, adviser registration, 3(c)(1) and 3(c)(7), accredited investor, qualified client, Form D, CFTC 4.13(a)(3), ERISA 25 percent, AIFMD, HSR, Re Inputs: q, authority |
canon_verify | Recompute a receipt from its inputs and confirm its id and outputs. Use it to check a number another agent or document claims came from this service. Inputs: receipt |

It answered our last check on 24 October 2026 in 225 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by wallstreet.wiki and served from canon.wallstreet.wiki, the vendor's own domain: https://canon.wallstreet.wiki/mcp.
13, as returned by the server's own tools/list on 23 September 2026: canon_batch, canon_changes, canon_cite, canon_compute, canon_contract, canon_describe_formula, canon_entity, canon_get_entry, and 5 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://canon.wallstreet.wiki/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
