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 →

How do I install the PolyAccounts accounting MCP server?
PolyAccounts accounting ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

Download bundleThe MCP registry declares no SHA-256 for this bundle, so there is no published digest to check it against. Open it with an MCPB-capable host such as Claude Desktop.
What is the PolyAccounts accounting MCP server?
PolyAccounts accounting is an MCP server listed in the public MCP registry as io.github.andrewblount/polyaccounts. Company-scoped accounting reads, writes and workflows. Supervised synthetic evaluation only. This page covers its MCPB bundle (https://github.com/andrewblount/polyaccounts-agent-kit/releases/download/v1.0.2/polyaccounts-hosted.mcpb).
Is the PolyAccounts accounting MCP server safe to use?
PolyAccounts accounting scores 50 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 PolyAccounts accounting MCP server expose?
PolyAccounts accounting exposes 12 tools: accounting_context, ledger_entries, trial_balance, describe_records, list_records, and 7 more. Their descriptions and schemas cost roughly 1,018 tokens of context every time the server is loaded.
What licence is the PolyAccounts accounting MCP server under?
PolyAccounts accounting declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the PolyAccounts accounting MCP server?
VerifyMCP ran 12 checks on PolyAccounts accounting, covering Source repository, Provenance, License, Maintenance and 8 more. 4 items could not be completed, a gap on our side rather than a finding about PolyAccounts accounting: Malware scan, Known CVEs, Install scripts and Dependency health. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an MCPB bundle, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
