mongodb-mcp-setupGuide users through configuring key MongoDB MCP server options.
Mongodb MCP Setup is an agent skill from mongodb/agent-skills, published by the product's own GitHub organization. Guide users through configuring key MongoDB MCP server options. Use this skill when a user has the MongoDB MCP server installed but hasn't configured the required environment variables, or when they ask about connecting to MongoDB/Atlas and don't have the credentials set up.
Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering NoSQL databases, MCP servers and Secrets management. It works with MongoDB, Model Context Protocol and Docker. The repository describes itself as: Use the official MongoDB Skills with your favorite coding agent to build faster. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 18b014e. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
dockerFrom the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
cloud.mongodb.commongodb.comdocker.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
MDB_MCP_API_CLIENT_SECRETAPI_CLIENT_SECRETFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Mongodb MCP Setup loads about 3.3k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 1,531 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/mongodb-mcp-setup/SKILL.md (or your agent's skills folder).This skill guides users through configuring the MongoDB MCP server for use with an agentic client.
The MongoDB MCP server requires authentication. Users have three options:
Connection String (Option A): Direct connection to a specific cluster
MDB_MCP_CONNECTION_STRING environment variableService Account Credentials (Option B): MongoDB Atlas Admin API access
atlas-connect-clusterMDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET environment variablesAtlas Local (Option C): Local development with Docker
This is an interactive step-by-step guide. The agent detects the user's environment and provides tailored instructions, but never asks for or handles credentials — users add those directly to their shell profile or agentic client config in Step 5. Make this clear to the user whenever credentials come up in Steps 3a and 3b.
Before anything else, determine which agentic client the user is running. This controls how credentials are configured in Step 1 and Step 5.
Run:
env | grep "^CODEX_"CODEX_* variables are present → the user is running a shell-based client (Claude, Cursor, Gemini CLI, Copilot CLI, etc.). Credentials are configured via shell profile environment variables.CODEX_* variables are present → the user is running Codex. Credentials are stored in ~/.codex/config.toml (macOS/Linux) or %USERPROFILE%\.codex\config.toml (Windows), not in shell environment variables. The desktop app does not inherit shell env vars when launched from Finder, Launchpad, or the Windows Start menu.Carry this client type (Codex vs. shell-based) forward through every subsequent step.
Check whether credentials are already configured.
For shell-based clients — check the current environment:
env | grep "^MDB_MCP" | sed '/^MDB_MCP_READ_ONLY=/!s/=.*/=[set]/'For Codex — search ~/.codex/config.toml (macOS/Linux) or %USERPROFILE%\.codex\config.toml (Windows):
grep -E 'MDB_MCP_(CONNECTION_STRING|API_CLIENT_ID|API_CLIENT_SECRET|READ_ONLY)' ~/.codex/config.toml 2>/dev/null | sed '/MDB_MCP_READ_ONLY/!s/[[:space:]]*=[[:space:]].*/ = "[set]"/'Interpretation (both):
MDB_MCP_CONNECTION_STRING appears → connection string auth is configuredMDB_MCP_API_CLIENT_ID and MDB_MCP_API_CLIENT_SECRET appear → service account auth is configured. If only one is present, treat it as incomplete.MDB_MCP_READ_ONLY appears → read-only mode is enabledPartial Configuration Handling:
config.toml for Codex, from their shell profile for shell-based clients), then proceed with Steps 2–5Important: If the user wants an Atlas Admin API action (managing clusters, creating users, performance advisor) but only has MDB_MCP_CONNECTION_STRING, explain they need service account credentials and offer to walk through setup.
If no valid configuration exists, present the options:
Connection String (Option A) — Best for:
Service Account Credentials (Option B) — Best for:
Atlas Local (Option C) — Best for:
Ask the user which option they'd like to proceed with.
If the user chooses Option A:
Explain where and how to obtain their connection string:
For MongoDB Atlas:
<username> and <password> with your database user credentialsFor self-hosted MongoDB:
mongodb://username:password@host:port/databaseExpected formats:
mongodb://username:password@host:port/databasemongodb+srv://username:password@cluster.mongodb.net/databasemongodb://host:port (local, no auth)Proceed to Step 4 (Determine Read-Only Access).
If the user chooses Option B:
Direct the user to create a MongoDB Atlas Service Account:
Full documentation: https://www.mongodb.com/docs/mcp-server/prerequisites/
Walk them through the key steps:
⚠️ CRITICAL: The user MUST add their IP address to the service account's API Access List, or all Atlas Admin API operations will fail.
Steps:
0.0.0.0/0 allows access from any IP — this is a significant security risk. Only use it as a last resort for temporary testing and remove it immediately afterward. It should never be used in production.This is more secure than global Network Access settings as it only affects API access, not database connections.
Proceed to Step 4 (Determine Read-Only Access).
If the user chooses Option C:
Verify Docker is installed:
docker infoIf not installed, direct them to: https://www.docker.com/get-started
Atlas Local requires no credentials — the user is ready to go:
atlas-local-create-deploymentatlas-local-list-deploymentsSkip Steps 4 and 5 (no configuration needed) and proceed to Step 6 (Next Steps).
Only applies to Options A and B. Skip to Step 6 for Option C.
Ask whether they want read-only or read-write access:
Read-Write (default): Full data access, modifications allowed
Read-Only: Data reads only, no modifications
If read-only: include the read-only flag in the credential snippet in Step 5. If read-write: omit it (defaults to read-write).
Proceed to Step 5 (Configure Credentials).
Do not ask for or handle credentials — provide exact instructions so the user can add them directly.
For shell-based clients — store credentials in a dedicated ~/.mcp-env file (not directly in the shell profile), then source it from the profile. This keeps credentials out of files that are often group/world readable by default and prevents accidentally committing them to git.
For Codex — add to ~/.codex/config.toml (macOS/Linux) or %USERPROFILE%\.codex\config.toml (Windows).
Show the user the appropriate snippet:
For Connection String (Option A):
Shell-based clients (~/.mcp-env):
export MDB_MCP_CONNECTION_STRING="<paste-your-connection-string-here>"Codex (config.toml):
[mcp_servers.mongodb.env]
MDB_MCP_CONNECTION_STRING = "<paste-your-connection-string-here>"For Service Account (Option B):
Shell-based clients (~/.mcp-env):
export MDB_MCP_API_CLIENT_ID="<paste-your-client-id-here>"
export MDB_MCP_API_CLIENT_SECRET="<paste-your-client-secret-here>"Codex (config.toml):
[mcp_servers.mongodb.env]
MDB_MCP_API_CLIENT_ID = "<paste-your-client-id-here>"
MDB_MCP_API_CLIENT_SECRET = "<paste-your-client-secret-here>"If read-only was chosen (Step 4), also add:
Shell-based: export MDB_MCP_READ_ONLY="true" in ~/.mcp-env.
Codex: MDB_MCP_READ_ONLY = "true" under the same [mcp_servers.mongodb.env] section.
⚠️ Both config.toml and ~/.mcp-env are stored in plaintext. Do not commit them to version control.
Restrict permissions on ~/.mcp-env:
# adjust for windows if needed
chmod 600 ~/.mcp-envAdd source ~/.mcp-env to the shell profile (e.g. ~/.zshrc). Adjust for the detected shell (e.g. for fish: bass source ~/.mcp-env or set -x; for PowerShell: dot-source a .ps1 file instead).
Detect the shell and profile file by running echo $SHELL if needed.
Shell-based clients — reload the profile first, then verify:
source ~/.zshrc # adjust to match the profile file
env | grep "^MDB_MCP" | sed '/^MDB_MCP_READ_ONLY=/!s/=.*/=[set]/'Codex:
# adjust path if on Windows
grep -E 'MDB_MCP_(CONNECTION_STRING|API_CLIENT_ID|API_CLIENT_SECRET|READ_ONLY)' ~/.codex/config.toml 2>/dev/null | sed '/MDB_MCP_READ_ONLY/!s/[[:space:]]*=[[:space:]].*/ = "[set]"/'Expected output shows the configured key(s) with values redacted to [set]. If nothing appears, check that credentials were saved and (for shell-based clients) that the profile was reloaded.
Proceed to Step 6 (Next Steps).
Restart the agentic client:
source <profile-file> to load the new variables, and reopen the client from that same terminal session so it inherits the environment.config.toml.Verify MCP Server: After restart, test by performing a MongoDB operation.

Guide users through configuring key MongoDB MCP server options. Mongodb MCP Setup is an agent skill from mongodb/agent-skills, published by the product's own GitHub organization. Guide users through configuring key MongoDB MCP server options.
Mongodb MCP Setup fits situations like: A user has the MongoDB MCP server installed but hasnt configured the required environment variables; they ask about connecting to MongoDB/Atlas and dont have the credentials set up.
Run `npx skills add mongodb/agent-skills --skill mongodb-mcp-setup -a claude-code`. Or copy the skill folder (skills/mongodb-mcp-setup in mongodb/agent-skills) into .claude/skills/mongodb-mcp-setup in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mongodb/agent-skills --skill mongodb-mcp-setup -a codex`. Or copy the skill folder (skills/mongodb-mcp-setup in mongodb/agent-skills) into .agents/skills/mongodb-mcp-setup in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mongodb/agent-skills --skill mongodb-mcp-setup -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mongodb-mcp-setup, .gemini/skills/mongodb-mcp-setup, .github/skills/mongodb-mcp-setup and .opencode/skills/mongodb-mcp-setup in your project.
Going by SKILL.md and its folder, Mongodb MCP Setup needs the command-line tools its instructions call (docker) and credentials named MDB_MCP_API_CLIENT_SECRET and API_CLIENT_SECRET. Our summary lists: Docker; A credential in MDB_MCP_API_CLIENT_SECRET; A credential in API_CLIENT_SECRET.
SKILL.md names 3 domains. As links in the text: cloud.mongodb.com, mongodb.com and docker.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Mongodb MCP Setup is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.3k tokens (SKILL.md is roughly 13k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
