What AgentFilings MCP server does

AgentFilings MCP server provides agent access to three finance-data areas: SEC filings, XBRL earnings information, and Form 4 insider trades. The listed company universe is the S&P 500, so it is intended for research involving companies in that index rather than an unrestricted universe of issuers.

The service is exposed at https://api.agentfilings.com. The available description identifies it as being for agents, but does not specify whether each data area is exposed as a separate MCP tool, resource, or another interface. Developers should therefore confirm the published API or MCP schema before implementing tool-specific calls.

How it works

An agent sends requests to the AgentFilings MCP server to retrieve information from the supported filing and market-data categories. The service uses x402 for per-call payment, meaning usage is described as transaction-based rather than as an explicitly documented free or subscription-only service.

The available material does not state the request format, response schema, authentication flow, supported date ranges, filing forms beyond Form 4, or rate limits. It also does not explain how XBRL earnings data is normalized or whether SEC filings are returned as raw documents, extracted fields, or both. Those details matter when deciding how to parse results and budget requests.

Limitations and notes

AgentFilings MCP server should be evaluated specifically for S&P 500 research workflows. The listing does not establish coverage for private companies, non-S&P 500 public companies, international issuers, or data outside SEC filings, XBRL earnings, and Form 4 trades.

No README or implementation documentation was provided with the listing. As a result, installation commands, environment variables, MCP transport, available client configurations, error behavior, payment setup, and exact tool names cannot be confirmed here. The service description supports the data categories and x402 per-call billing model, but not claims about freshness, completeness, historical depth, analytical features, or production guarantees.

Before integration, verify how an MCP client connects to https://api.agentfilings.com, how x402 payment is authorized, which S&P 500 identifiers are accepted, and what fields each response returns. These checks are especially important for agents that need repeatable financial analysis or automated insider-trade monitoring.
