Overview

AI-generated overview

Lets an assistant cross-check a factual claim against a verified knowledge graph before asserting it.

What you can do
Spectral is a remote MCP endpoint that checks a factual claim against a verified knowledge graph. According to its description, it cross-checks claims before they are asserted and never guesses. No tool list is published, so the exact operations available are not documented here.
When to use it
Worth considering when an assistant needs to verify factual claims before stating them, for example in fact-checking or answer-generation workflows where unsupported assertions are a risk.
Requirements
A remote MCP client that supports the streamable HTTP transport, pointed at the provider's endpoint. No authentication, environment variables, headers, or local packages are declared.
Before you install
The service is remote, so any claim text submitted is sent to a third party. No authentication is declared, so it is unclear how access is controlled or rate-limited. The tool list is not published, so verify behavior before relying on it.

Installation

In SourceWeft

  1. Open Spectral — verified-knowledge oracle in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.seespectral%2Foracle/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Score

17% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.

  • DescriptionRequired15 pts
  • Logo10 pts

    Publish an icon in the registry entry.

  • Documentation15 pts

    Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.

  • LicenseNot applicable

    A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
