Set up

Add Context7 to Hermes in four steps

Admins approve the server once. Everyone in Hermes then gets it through the same governed connection.

  1. 1

    Approve Context7 in Runlayer

    Add Context7 from the catalog and choose who can use it and which of its tools are allowed.

  2. 2

    Connect Hermes to Runlayer

    Users add the Runlayer Plugin to Hermes by following Runlayer’s setup guide. Hermes reaches Context7’s 2 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Context7

    Sign in the way Context7 requires. Runlayer holds the credentials so they stay out of the client’s configuration.

  4. 4

    Use Context7 from Hermes

    Context7’s approved tools appear in Hermes. Every call is checked against policy and recorded.

Tools

2 Context7 tools in Hermes

Runlayer policy decides which of these Hermes users can call. 2 read data only.

  • Query docs

    Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework.

  • Resolve library ID

    Resolves a package/product name to a Context7-compatible library ID and returns matching libraries.

Control

What Runlayer can see and stop in Hermes

Some controls apply to every client at the gateway. Others depend on what Hermes exposes to Runlayer.

  • Gateway policy (available)

    Every Context7 call from Hermes passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Hermes as the client, the tool, and the policy and scanner decisions.

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Hermes runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output in Hermes and show a message in its place.

  • Redact output in place (not available)

    Hermes cannot take masked output, so Runlayer can block a tool’s output but not mask it. The gateway still applies policy to the call.

In Hermes

  • Hermes can replace blocked tool output with a message, but its after-call event is for monitoring only.
