Overview

AI-generated overview

Connects an assistant to Polygon's market data API for stocks, crypto, ETFs, analyst ratings, earnings and financial news.

What you can do
  • Retrieve stock, crypto and ETF market data
  • Look up analyst ratings and earnings information
  • Read financial news
  • Expose the full upstream API surface as tools, with parameter validation, retries and optional response redaction
When to use it
Useful when an assistant needs live market quotes, fundamentals, ratings or news for research, reporting or analysis, and you already have Polygon API access.
Requirements
Runs locally as a Python package (uvx mcparmory-polygon) or a Docker image; Python 3.11+ for the package. The manifest declares no auth or environment variables, but the registry notes each server's own README covers credential setup, so a Polygon API key is likely required.
Before you install
The manifest declares no credentials, yet the registry states servers support API key, bearer, basic, OAuth2 and other auth, so expect to supply a Polygon API key. Polygon plans are typically rate-limited or paid, so heavy use may consume quota or incur cost. Tool list is not published here, so verify the exposed endpoints before relying on it.

Installation

In SourceWeft

  1. Open Polygon in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MCP servers that connect AI agents to real-world APIs. Each server is a standalone Python package — generated from the upstream OpenAPI spec using MCP Blacksmith and tested against the live API before release. Hosted on MCP Armory or run independently.

Install & Usage

Every server is a standalone PyPI package (mcparmory-<server-name>). Each server's own README.md has full credential setup and configuration instructions.

bash
# With uvx (no install needed)uvx mcparmory-github
# With pippip install mcparmory-githubmcparmory-github

MCP client configuration (Claude Desktop, Cursor, Codex, Claude Code):

json
{  "mcpServers": {    "github": {      "command": "uvx",      "args": ["mcparmory-github"],      "env": {        "BEARER_TOKEN": "ghp_your_token_here"      }    }  }}

Features

Every server in this registry provides:

  • Full API coverage — all endpoints from the OpenAPI spec are exposed as MCP tools
  • Authentication — API key, Bearer token, Basic auth, OAuth2, JWT, OpenID Connect, and mutual TLS
  • Multi-auth — servers that support multiple auth methods let you configure whichever you prefer
  • Pydantic validation — request parameters are validated before sending to the API
  • Resilience — configurable retries with exponential backoff, connection pooling, and timeouts
  • Response sanitization — optional redaction of sensitive fields from API responses

How servers are generated

Servers are generated by MCP Blacksmith, an automated pipeline that:

  1. Parses an OpenAPI specification
  2. Transforms operations through LLM-driven passes (naming, parameter filtering, enhancement, classification)
  3. Generates a complete MCP server with auth, models, validation, and configuration
  4. Tests every tool against the live API using an autonomous agent
  5. Deploys passing servers to this registry

The generator targets Python 3.11+ and uses FastMCP as the MCP framework.

Contributing

Servers are auto-generated — don't edit server code directly. If you find an issue, open a GitHub Issue describing:

  • Broken or deprecated endpoints
  • Missing or incorrect parameters
  • Authentication problems
  • Incorrect request/response models

We'll re-generate the affected server with the fix. To request a new server, open an issue with a link to the API's OpenAPI spec or documentation.

Each generated server is released under the MIT License. The underlying APIs have their own terms of service — see individual server READMEs for details.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
