get_mcp_server

Retrieve full details for a specific server by its MCPVault slug.

Parameters:

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | slug | string | Yes | MCPVault slug visible in the listing URL: mcpvault.io/servers/<slug> |

Returns: name, description, grade, status, verification date, GitHub repo, stars, license, client compatibility, topics, tool list, and listing URL.

Example prompts:

• "Get details for the github MCP server"
• "What clients does the postgres-mcp server support?"

get_install_command

Get the install command for a specific MCP server.

Parameters:

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | slug | string | Yes | MCPVault slug for the server |

Returns the recorded install command and a link to the listing page. If no install command is on record, points to the listing for manual setup instructions.

Example prompts:

• "What is the install command for filesystem-mcp?"

submit_mcp_server

Submit a GitHub repository to MCPVault as a new MCP server listing. If you find an MCP server on GitHub that is not yet in MCPVault, use this tool to add it. The repository is validated against the MCPVault plausibility gate (the repo name, description, or topics must mention "mcp" or "model context protocol"). Rate limited to 5 submissions per client per day.

Parameters:

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | repo_url | string | Yes | Full GitHub repository URL, e.g. https://github.com/owner/repo |

Responses:

• Submitted successfully: returns the listing URL and a note that the owner can claim it at mcpvault.io/claim.
• Already listed: returns the existing listing URL.
• Not an MCP server: explains what the plausibility gate checks.
• Rate limited: try again tomorrow.

Example prompts:

• "If you find an MCP server on GitHub that is not in MCPVault, submit it"
• "Submit https://github.com/owner/my-mcp-server to MCPVault"
• "Add this MCP server to MCPVault: https://github.com/owner/repo"

Evidence and limitations

• verified means MCPVault completed a live MCP handshake at the recorded time. It is not a security audit.
• Grades summarize repository activity, maintenance, documentation, and reliability signals. They are not sold and do not guarantee safety.
• stale means the maintainer has not claimed the imported record. It does not mean the software is abandoned.
• Install commands and compatibility data come from public metadata and maintainer edits. Review the linked repository before running third-party code.
• This server sends search and submission requests to https://mcpvault.io. It does not read local files, credentials, prompts, or client conversations.

Support and security

For usage help, open an issue or contact [email protected]. For a security concern, do not include secrets in a public issue. Email the same address with SECURITY in the subject.

See CHANGELOG.md for release notes.
