The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Install

How do I install the OpenFile MCP server?

OpenFile is a hosted endpoint at https://mcp.joinopenfile.com/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the OpenFile MCP server?

OpenFile is an MCP server listed in the public MCP registry as com.joinopenfile/openfile. Form U.S. companies and file U.S. trademarks. The agent prepares the filing and the owner signs it. This page covers its hosted endpoint (https://mcp.joinopenfile.com).

Is the OpenFile MCP server safe to use?

OpenFile scores 66 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the OpenFile MCP server expose?

OpenFile exposes 27 tools: search_docs, read_doc, plan_task, get_pricing, quote_application, and 22 more. Their descriptions and schemas cost roughly 3,120 tokens of context every time the server is loaded.

Does the OpenFile MCP server require authentication?

No. We connected to OpenFile without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the OpenFile MCP server still maintained?

OpenFile is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
