# Mailforge: MCP server status, API access gate and what it does > Shared cold-email infrastructure platform (part of the Salesforge "Forge Stack") - automates workspace setup,...

No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 1. Vendor: [mailforge.ai](https://mailforge.ai) · entry id 09-mailforge · source 09-email-deliverability.md line 140 **What it does** Shared cold-email infrastructure platform (part of the Salesforge "Forge Stack") - automates workspace setup, domain purchase/checks, mailbox creation, DNS records, forwarding, and domain masking for high-volume outbound. **AI features, separated from automation with an AI label on it** No AI-specific capability confirmed; infrastructure automation (bulk domain/mailbox provisioning, DNS configuration) reads as rules-based automation, not model-driven. **RevOps role** Shared (non-dedicated-IP) cold-email infrastructure layer - the lower-cost counterpart to Infraforge's dedicated-IP offering within the same product family. **MCP server** - **Status bucket**: Official MCP - **Auth**: API key, generated from the Mailforge dashboard. - **Parsed URLs**: 1 found in the mcp_url field - **Endpoint probe**: answered, asking for a key - **Endpoint URL**: [https://mcp.salesforge.ai/mcp](https://mcp.salesforge.ai/mcp) - **Probed**: 2026-09-04, HTTP 401 The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-08-24. On 2026-09-04 the recorded URL answered an MCP initialize as a server, which is liveness and nothing more: nobody has run its tools. mcp_status, verbatim from the file: official mcp_url, verbatim from the file: https://mcp.salesforge.ai/mcp - [https://mcp.salesforge.ai/mcp](https://mcp.salesforge.ai/mcp) **What this server exposes** Not harvested yet. Unmeasured, not empty: nobody has read this server's tool list, so this page says nothing about what it exposes. 141 of the 741 entries that record an official or community MCP server carry a harvested tool list. The other 600 are unmeasured, which is not the same as empty. Harvest last run 2026-09-27. The full roll up is on the [tools index](../tools-index.md). **Command line** No CLI found by the 2026-09-27 harvest across vendor docs, npm, PyPI, Homebrew and GitHub. That is a probe result, not proof of absence. **Access gate** - **Gate bucket**: Paid, self-serve - **Can a solo operator reach it**: Yes, by paying, no sales call api_gate, verbatim from the file: paid - no free tier found; positioned for "scaling shared cold email infrastructure and bulk mailbox management." **API documentation** No documentation URL recorded. 727 of 1252 entries are in the same position. Blank is legal and it is published as blank. **GitHub health** Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build. The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale. **On GitHub** The entry carried no github.com URL and the organisation search returned nothing on 2026-09-08. That is a statement about the instrument on that date, not proof the vendor has no GitHub. **Jobs it can do** - [Provision sending infrastructure](../jobs/provision-sending-infrastructure.md) A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records. Tagged by machine-pass on 2026-08-25 against the closed 56 job vocabulary. 271 of 1,252 entries carry at least one tag; 849 tags are assigned in total. **Sources** - [https://mcp.salesforge.ai/mcp](https://mcp.salesforge.ai/mcp) - [https://www.mailforge.ai/blog/mailforge-api](https://www.mailforge.ai/blog/mailforge-api) - [https://help.salesforge.ai/en/articles/10333582-salesforge-mcp-server-with-claude-for-cold-email-and-linkedin-outreach](https://help.salesforge.ai/en/articles/10333582-salesforge-mcp-server-with-claude-for-cold-email-and-linkedin-outreach) - [https://www.salesforge.ai/blog/cold-email-mcp-server](https://www.salesforge.ai/blog/cold-email-mcp-server) 4 source URLs.

This is one of the more mature vendor-published MCP rollouts found in this entire file. **Provenance** - **Entry id**: 09-mailforge - **Source file**: 09-email-deliverability.md - **Source line**: 140 - **Tier**: RESEARCHED - **last_checked**: 2026-08-24 - **Data baked**: 2026-09-27 Every field above is rendered from directory.json exactly as the build produced it.
