Loki Mode vs Stepgate
A side-by-side look at the Loki Mode and Stepgate MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Loki Mode for coding agents work as a local process; choose Stepgate for coding agents as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Loki Mode when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.
Choose Stepgate when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
TAVILY_API_KEY. - You want tools like
stepgate_call, stepgate_submit, stepgate_guide.

Stepgate tools 8
stepgate_callCalls one of the current step's operations for a Stepgate run and returns its result. Stepgate makes the request and adds any credentials.stepgate_submitSubmits the current step's output for a Stepgate run. Returns the next step, the gate failures to fix, or the finished run's outputs.stepgate_guideReturns how to write a stepfile: the authoring workflow, the full format reference and the JSON Schema. Call it before writing or editing a stepfile.stepgate_examplesLists the catalog's stepfiles, or with a name returns that stepfile's YAML and README, to copy a working pattern from.stepgate_validateChecks a draft stepfile against the schema and every load-time rule. Returns each issue with its path, or the stepfile's identity and whether stepgate_try accepts it.stepgate_inspect_apiFetches a public OpenAPI document or MCP server without credentials and reports what a stepfile needs: the document's sha256, servers, security schemes and operationIds, or an MCP server's tools and their schema_sha256.stepgate_outlineTurns a SKILL.md or markdown SOP into a skeleton stepfile: one step per numbered item or second-level heading, each rule it states marked as a gate to write, and TODO markers where only an author can decide. stepgate_validate lists the markers left.stepgate_tryStarts a run of a draft stepfile from its text, without adding it to the server. Drive it with stepgate_call and stepgate_submit. Drafts may call only public https URLs, and use only the credentials and settings the operator granted to drafts.

Frequently asked questions
Loki Mode is categorized under Coding Agents and uses a local stdio subprocess. Stepgate belongs to Coding Agents and uses a local stdio subprocess. Pick Loki Mode for coding agents work and Stepgate for coding agents.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Loki Mode is bring-your-own-key: usage is billed by the API provider you supply a key for. Stepgate has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add loki-mode and stepgate as separate keys in the same mcpServers object, and your assistant will call tools from either one.
