Questions

doh-mcp

MCP server for DNS-over-HTTPS (DoH). Resolves names and fetches URLs through a DoH resolver so an agent keeps working behind an ISP DNS block or a poisoned resolver. No API key. A single Go binary, CGO-free.

License: Apache-2.0

Install

Build from source

git clone https://github.com/99apps-id/doh-mcp.git
cd doh-mcp
go build -o doh-mcp .

Download binary

Pre-built binaries are available for Linux, macOS, and Windows on the GitHub Releases page.

Configure

The server accepts a -resolver flag:

doh-mcp -resolver cloudflare
# or
doh-mcp -resolver google
# or
doh-mcp -resolver quad9
# or
doh-mcp -resolver adguard
# or
doh-mcp -resolver https://your-doh-server/dns-query

Available built-in resolver aliases:

cloudflare (default)
google
quad9
adguard

Or pass any DoH endpoint URL that answers the JSON API (Accept: application/dns-json).

Tools

Tool	What it does
`doh_resolve`	Resolve a name (A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA) through a DoH resolver and return the records with TTL.
`doh_compare`	Resolve a name with the system resolver and through DoH and report whether they agree, which detects a block, a hijack or a local override.
`doh_fetch`	Fetch an http(s) URL, resolving its host through DoH and dialing the resolved address, so a DNS block does not stop the read. HTML is reduced to text.

Editor and Agent Compatibility

This MCP server is designed to work with any MCP client, including:

Termigo - native integration via ~/.termigo/mcp.json
Termixgo - ~/.termixgo/config.json or mcpServers section
VS Code (with MCP extension)
Claude Code (Anthropic's CLI)
Codex (OpenAI's coding agent)
Cursor
OpenCode
OpenClaw
Hermes
9router
Windsurf
Zed
Cline
Any other editor or agent that supports the Model Context Protocol (MCP) over stdio

Generic MCP Configuration

All MCP clients that support stdio servers can use this format:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Replace doh-mcp with the full path to the binary on your system:

Linux: /usr/local/bin/doh-mcp or $HOME/.local/bin/doh-mcp
macOS: /usr/local/bin/doh-mcp or $HOME/.local/bin/doh-mcp
Windows: C:\\Users\\<USER>\\bin\\doh-mcp.exe or C:\\Program Files\\doh-mcp\\doh-mcp.exe

Termigo

mcpServers in ~/.termigo/mcp.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Tools appear as mcp_doh__doh_resolve, mcp_doh__doh_compare, mcp_doh__doh_fetch.

Termixgo

mcpServers in ~/.termixgo/config.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Or use the built-in MCP commands:

termixgo mcp add doh --command doh-mcp --arg -resolver --arg cloudflare
termixgo mcp list

VS Code (GitHub Copilot, Cline, Continue)

VS Code uses mcpServers in .vscode/mcp.json (workspace) or user settings:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Claude Desktop / Claude Code

Claude Desktop uses mcpServers in claude_desktop_config.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Claude Code reads from ~/.claude.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Cursor

Cursor uses mcpServers in ~/.cursor/settings.json or workspace .cursor/settings.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

OpenCode

OpenCode uses .opencode/mcp.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

OpenClaw

openclaw mcp add doh --command doh-mcp --arg -resolver --arg cloudflare
openclaw mcp doctor doh --probe

Hermes

Hermes uses mcp_servers in ~/.hermes/config.yaml:

mcp_servers:
  doh:
    command: doh-mcp
    args:
      - "-resolver"
      - "cloudflare"

9router

9router uses the MCP Marketplace UI or managedMcpServers in the workspace config:

{
  "managedMcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Or use the Dashboard UI: Plugins -> Add Custom MCP -> paste the command above.

Codex CLI

Codex CLI reads from OPENAI_MCP_SERVERS environment variable:

export OPENAI_MCP_SERVERS='{"doh":{"command":"doh-mcp","args":["-resolver","cloudflare"]}}'

Or in .codex/config.json:

{
  "mcpServers": {
    "doh": {
      "command": "doh-mcp",
      "args": ["-resolver", "cloudflare"]
    }
  }
}

Docker

docker build -t doh-mcp .
# point the client at: docker run -i --rm doh-mcp

Dockerfile:

FROM golang:1.26-alpine AS build
WORKDIR /app
COPY . .
RUN go build -o doh-mcp .

FROM alpine:latest
RUN apk add --no-cache ca-certificates
COPY --from=build /app/doh-mcp /usr/local/bin/doh-mcp
ENTRYPOINT ["doh-mcp"]

Example calls

// doh_resolve
{ "name": "example.com", "type": "A", "resolver": "cloudflare" }

// doh_compare
{ "name": "duckduckgo.com" }

// doh_fetch
{ "url": "https://example.com", "max_chars": 20000 }

doh_compare is the diagnostic: on a blocked network it reports the system resolver failed but DoH resolved the name; DNS is blocked or poisoned.

Security

doh_fetch refuses cloud metadata (169.254.169.254, metadata.google.internal) and link-local addresses, re-checks on every redirect, and pins the connection to the address it resolved, which also defeats DNS rebinding. Loopback and private addresses are allowed, so a local documentation server can be read.
