Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

  • Teams already using Exa that can test with non-sensitive data and least privilege.
Not ideal for
  • The tool can fetch HTTP/HTTPS URLs and read local file URIs, so it should be treated as a trusted local capability. Microsoft explicitly warns against binding HTTP/SSE to non-local interfaces without understanding the security implications.

Access and data
AuthenticationNo authentication is supported by the MCP server.Authentication follows the publisher's documented endpoint or local-server configuration. OAuth scopes, API-key handling, and revocation behavior remain review items.
CostNo separate MCP fee is documented for the open-source package.No MCP100 cost conclusion is published yet. The publisher's account plan, API usage, infrastructure, or per-action charges may apply.
PermissionsThe process runs with the privileges of the local user and `convert_to_markdown` can read any file that user can access plus HTTP/HTTPS/data URIs.Exact permissions and the read/write boundary have not yet completed MCP100 independent review; consult the linked publisher sources and use the narrowest available scope.
Data handlingConversion runs in the local server process. Local files or remote URLs selected by the caller are read and converted to Markdown.Publisher-accessible account or application data may be returned to the MCP client and its selected model. Retention and subprocess behavior require candidate-specific review.
Limitations
Tradeoffs
  • Shortlist evidence is sufficient for identity, setup and task value; authenticated runtime tool-schema measurement and exhaustive security certification remain out of scope.
  • First-party provenance and a clear task improve confidence, but do not replace an independent permissions and usability review.
  • Client transport compatibility does not prove that authentication, scopes, failure handling, and every tool behave safely.
Risk contextThe tool is a powerful local file/network reader. Exposing HTTP/SSE beyond localhost can give other network users access to files and network resources available to the server account.Use a test workspace or non-production account, least privilege, read-only controls where available, explicit approval for mutations, and credential revocation after evaluation.
