• rate_tool

  IA-QA — 130+ QA & Dev Tools for AI Agents

  Give honest usage feedback on an IA-QA MCP tool. Provide a score (1-5) and a comment. Rate low (1-2) if the tool was wrong, irrelevant, or a poor fit; rate high (4-5) only if it genuinely solved your need. Ratings are aggregated on a public dashboard at /devtools/mcp-ratings. Skip rating routine successes — we want signal, not praise. Example: rate_tool({ tool_name: "format_json", score: 2, comment: "Tried to pretty-print a JSON5 file, it rejected trailing commas — not usable for my case." })

• ping

  nara-tour

  Connectivity check — returns server version and current timestamp. Use to verify MCP server is reachable before calling other tools.

  Connector

• publish_template

  Kamy

  Make a template version live for rendering. Called with no `version`, it snapshots the current draft into a new version and points published_version at it — this is how you ship an edit made with update_template. Called with an existing `version`, it republishes that earlier snapshot and leaves the draft alone. Reach for rollback_template instead when you are reverting a bad release: only that tool offers the concurrency fence and the option to restore the draft as well. Takes a template UUID or slug, same as every other /v1/templates route. Returns { templateId, publishedVersion, publishedVersionId, latestVersion, publishedAt }. Requires a Kamy API key with the `templates:write` scope; without a key, returns dashboard setup instructions.

• axint.doctor

  Axint

  Audit the current Axint runtime and project wiring: running MCP version, expected version, Node/npm/npx paths, project .mcp.json, AGENTS.md, CLAUDE.md, .axint/project.json, and Xcode Claude Agent registration. Use this when an agent might be connected to a stale Axint process or when a new project needs first-try MCP setup proof. Use: call when MCP wiring, package paths, Xcode setup, or project memory may be stale; use run for build proof. Inputs: cwd selects the project; expectedVersion turns a runtime mismatch into a blocker. Effects: read-only inspection; writes no files; no auth or network required.

• postgres_upgrade_precheck

  mcp

  Checks if a Cloud SQL for PostgreSQL instance is ready for a major version upgrade to the specified target version. The `target_database_version` MUST be provided in the request (e.g., `POSTGRES_15`). This tool helps identify potential issues *before* attempting the actual upgrade, reducing the risk of failure or downtime. This tool is only supported for PostgreSQL primary instances and does not run on read replicas. The precheck typically evaluates: - Database schema compatibility with the target version. - Cloud SQL limitations and unsupported features. - Instance resource constraints (e.g., number of relations). - Compatibility of current database settings and extensions. - Overall instance health and readiness. This tool returns a long-running operation. Use the `get_operation` tool with the operation name returned by this call to poll its status. IMPORTANT: Once the operation status is DONE, the detailed precheck results are available within the `Operation` resource. You will need to inspect the response from `get_operation`. The findings are located in the `pre_check_major_version_upgrade_context.pre_check_response` field. The findings are structured, indicating: - INFO: General information. - WARNING: Potential issues that don't block the upgrade but should be reviewed. - ERROR: Critical issues that MUST be resolved before attempting the upgrade. Each finding should include a message and any required actions. Addressing any reported issues is crucial before proceeding with the major version upgrade. If `pre_check_response` is empty or missing, it indicates that no issues were identified during the precheck. Running this precheck does not impact the instance's availability.

• dossier_cors

  drwho.me

  Core dossier check: Send a CORS preflight OPTIONS request to https://<domain>/ and return the access-control-* response headers. Use to verify CORS policy for a specific origin-method pair, or to check whether a domain allows cross-origin requests; provide origin and method to simulate a precise preflight, or omit to use defaults (origin: https://domainposture.com, method: GET). Single OPTIONS request via fetch, 5 s timeout. Returns a CheckResult: on success, {status:"ok", headers:{access-control-allow-origin,...}}; on failure, {status:"error", reason}.

• create_notification

  Courier

  Create a V2 notification template. name is required. Provide content inline or set it immediately after creation via put_notification_content. To send with this template you must publish it first via publish_notification (or pass state: 'PUBLISHED' on create). Link a routing strategy via notification.routing.strategy_id to control which channels are used. Example: { notification: { name: 'welcome-email', tags: [], brand: null, subscription: null, routing: { strategy_id: 'rs_01abc' }, content: { version: '2022-01-01', elements: [] } } }.

• strale_ping

  Strale - 290+ API capabilities for AI agents

  Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.

• regenerate_image

  WebZum - The Hosting Layer for AI-Generated Web Content

  Regenerate one image inside a specific section of a WebZum site. Creates a new version with a freshly AI-generated image for that section and reassembles. Use the optional userMessage to steer the new image — "show a wider shot", "change the angle", "make it sunset lighting", etc. Required: businessId, versionId, sectionId. Returns { versionId, status: 'completed' | 'in_progress', ...extra }. If status is 'in_progress', poll get_site_status with the returned versionId every 5-10s until isComplete is true. Concurrency: edits on the same businessId MUST be serial. Never fire parallel edit calls on the same site.

• account_api_key_status

  SAVORDISH

  Check the status of the API key you're using right now — see call count, rate limit, and creation date. Useful for monitoring your MCP usage. TRIGGERS: - 'check my API key', 'API key status', 'how many calls have I made' - 'my usage', 'rate limit status', 'key info'

• get_component

  Uploadkit

  Fetch full metadata plus a ready-to-paste React usage example for one specific UploadKit component. When to use: once you know the exact component name (from list_components or search_components) and need to show the user how to drop it into their code. The returned "usage" field is copy-pasteable TSX including the correct import line and the styles.css import. Returns: JSON { name, category, description, inspiration, usage }. If the name does not match any component, returns a suggestion message with the 5 closest matches. Read-only, idempotent.

• get_mcp_usage_self

  storyflo

  Return the caller's own trailing 30-day MCP tool-usage summary: total calls, success rate, p50 latency, and per-tool call/error counts. Identity is resolved from the OAuth bearer token on this request — anonymous callers receive a zeroed shape. Use this to self-budget against rate limits, audit which tools your agent actually uses, or decide whether a paid tier is worth the spend. Read-only, no side effects.
