Exposes a typed, provenance-aware knowledge graph over an Obsidian vault to coding agents over MCP, so they can trace what grounds a claim, compute which other notes a change makes wrong, surface contradictions and admitted gaps, and assemble a task-specific token-budgeted subset of the vault. Indexing, retrieval, and impact analysis run with zero third-party runtime dependencies beyond the Python standard library.

Enables AI agents to search, browse, download, favorite, comment on, and post-process comic albums via standardized MCP tools, with asynchronous download tasks, progress tracking, cancellation/retry, runtime configuration, and account login.

Enables AI assistants to manage task lists, tasks, subtasks, due dates, notes, and completion through the Google Tasks API, including reversible completion and syncing changes.

Enables Claude to explore, query, and modify MongoDB databases through natural language, including CRUD operations, aggregation, indexing, and administrative tasks.

Exposes five prompt-engineering skills as MCP tools, prompts and resources so a connected AI client can itself prepare and execute task, system-prompt, evaluation and rewrite work. It also provides a durable, resumable pipeline that tracks isolated worker dispatches, validates stage output, enforces loop limits and persists run artifacts — locally over stdio or self-hosted on Cloudflare Workers without any model API key.

Enables applications and AI agents to inspect, convert, extract, and process media through asynchronous HTTP and MCP tasks, with optional natural-language planning and A2A interoperability.

Enables agents to persist and resume long-horizon tasks using cryptographic event-sourced checkpoints, idempotency deduplication, scheduled heartbeats, pause/resume tokens, and fail-safe recovery.

Enables long-horizon autonomous task checkpointing and resumption through cryptographic event-sourced state persistence, idempotency key deduplication, timeout heartbeats, human-in-the-loop pause/resume tokens, and fail-safe recovery.

Enables Claude Code and OpenAI Codex CLI to act as bidirectional partners by letting each ask the other for code review, explanations, planning, performance analysis, and implementation help. It also provides background job tools for starting, observing, waiting on, and cancelling delegated tasks.

Automate tax workflow tasks and manage client engagements. Track deadlines, organize documents, and handle billing for accounting firms.

Enables users to mint reusable local MCP integrations from website tasks and run the generated business tools through Codex, with chat-based job progress, input prompts, cancellation, and authenticated browser operations.

Revnuvo MCP server for the agent economy. Tools: verify domains, resolve DNS, assess domain trust/risk, register agents, create tasks, submit results, verify task outputs, and get agent reputation leaderboard. The canonical developer home for the Revnuvo x402 ecosystem — SDK, Gateway, and Resource APIs is developers.revnuvo.site

Enable your LLMs to perform accurate numerical calculations with a simple API. Leverage basic arithmetic and statistical functions to enhance your applications. Simplify complex mathematical tasks effortlessly and improve your model's capabilities.

Enables managed access to workspace file operations, background tasks, Skills, and upstream MCP services through a unified web console with workspace-bound keys and explicit tool permissions.

Connects the web version of ChatGPT to a local Windows development environment, letting the chat read project files, search and edit code, run commands and tests, and build or verify release artifacts through natural language. It also provides isolated Git worktree runs, resumable background tasks, per-directory permission limits, and desktop notifications for unattended coding workflows.

Lets Claude Code delegate bounded coding tasks to a GLM model as a sub-agent through a single MCP tool that reads, writes, edits, lists directories, and runs shell commands inside a specified project folder. Each run returns only a short report with changed files and token usage, keeping GLM's intermediate tool traffic out of Claude's context.

Streamline technical workflows with a comprehensive suite of data transformation and validation utilities. Convert between diverse formats like JSON, CSV, and Markdown while managing encodings and identifiers efficiently. Enhance productivity by performing complex text analysis, regex testing, and timestamp conversions instantly.

Enables AI apps to manage Google Calendar in plain language, including reviewing schedules, creating and changing events with guests and Google Meet, finding free time, and blocking Out of Office or Focus Time.

Enables managing GitHub Actions workflows through MCP, including listing and inspecting workflows, triggering workflow_dispatch and repository_dispatch events, and monitoring or canceling workflow runs.

Enables Codex users to delegate engineering, refactoring, auditing, and test execution tasks to Google Antigravity CLI as a persistent autonomous subagent, with tools for managing sessions and running prompts.

Enables turning Gmail messages and natural-language requests into reviewed, workload-aware Things 3 tasks, with read-only Gmail access and explicit approval before anything is created.

Local macOS MCP server for Calendar and Reminders that gives each AI agent its own token and access to only the calendars and reminder lists you choose, per action. Writes can require your approval in a panel that shows every field.

Enables LLMs to analyze Python repositories structurally via AST and call graphs, providing code search, symbol lookup, change-impact analysis, workflow tracing, and explanation without embeddings.

Enables AI agents to manage tasks through a board with backlog, ready, in-progress, and done columns, plan daily work, track velocity, forecast backlog completion, and leverage rule-based or DeepSeek-powered recommendations.
