Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

canon

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.

canon_changes

Aggregated dated change events across every vertical, newest first. Poll this instead of re-crawling.

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.

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 a working example instead of nulls.

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/compare over REST.

canon_describe_formula

Input schema with ranges and defaults, output names, stated convention, citations and test vectors for one 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.

canon_get_entry

Full definition and notes for one entry, by site and id (ids come from canon_search).

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.

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, Reg T. Each row carries the rule, authority, effective date, primary source and a confidence label. Filter by words or 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.

Canon (wallstreet.wiki) — questions

Answers built from our own checks of this server.

What can Canon (wallstreet.wiki) do?

It exposes 13 tools, read directly from the server on our last check. Among them: canon_batch, canon_changes, canon_cite, canon_compute, canon_contract, canon_describe_formula and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Canon (wallstreet.wiki) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 290 ms. The bar chart above shows every period we have measured.

How do I connect Canon (wallstreet.wiki)?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Canon (wallstreet.wiki) need an API key?

No. Canon (wallstreet.wiki) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Canon (wallstreet.wiki)?

It answers our handshake in 290 ms on average, which is faster than 52% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
