Overview

AI-generated overview

A remote MCP endpoint that looks up finance canon entries and runs 30 deterministic formulas, each returning a verifiable receipt.

What you can do
Canon (wallstreet.wiki) is a remote MCP server reachable over streamable HTTP at canon.wallstreet.wiki. According to its registry description, it offers finance canon lookup plus 30 deterministic formulas, each accompanied by a verifiable receipt. No tool list is published in the manifest, so the exact tool names and inputs are not documented here.
When to use it
Consider it when an assistant needs finance reference lookups or deterministic formula results that come with a receipt for verification. It is less useful if you need documented tool schemas before connecting, since none are listed.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to canon.wallstreet.wiki. No authentication, environment variables, headers, or packages are declared.
Before you install
The server is remote, so lookups and formula inputs are sent to a third party at canon.wallstreet.wiki. No credentials are declared, but confirm the provider's data handling before sending anything sensitive. The receipt mechanism is claimed in the description and is not independently verified here.

Installation

In SourceWeft

  1. Open Canon (wallstreet.wiki) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/wiki.wallstreet%2Fcanon/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Tools

canon_sites

List canon sites

The sites in the .wiki finance canon with live entry counts and review dates.

Takes no parameters.

canon_get_entry

Get one canon entry

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

Parametersidrequiredsiterequired

canon_changes

What changed in the canon

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

Parameterssince

canon_list_formulas

List formulas

The deterministic formula registry: id, site, summary, input names and citations. Call canon_describe_formula for a schema.

Takes no parameters.

canon_describe_formula

Describe a formula

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

Parametersformularequired

canon_compute

Compute with a receipt

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.

Parametersinputsrequiredformularequired

canon_verify

Verify a receipt

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.

Parametersreceiptrequired

canon_batch

Compute many formulas at once

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.

Parametersitemsrequired

canon_entity

Resolve a US issuer

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.

Parametersqrequiredlimit

canon_thresholds

Regulatory 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.

Parametersqauthority

canon_contract

Prediction-market contract, normalised

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.

Parametersidrequiredvenuerequired

canon_cite

Cite a canon entry

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.
