Self-hosted persistent memory for coding agents: hooks capture what you do, and an MCP server lets any agent recall it across sessions and across tools.
Also: Coding Agent, Open Source
-
by Sourcegraph
Sourcegraph's MCP server — cross-repository keyword and semantic code search, go-to-definition, find-references, commit and diff search, and Deep Search, served from your own instance.
Also: Code Search

Also: Code Search
-
by Vladislav Shulcz
Indexes the coding-agent sessions already sitting on your disk — months of history from before you installed it — and serves them back over MCP. 3.5 GB searched in ~1.5 ms, no LLM, no embeddings.
Also: Coding Agent
-
by mksglu
MCP server and Claude Code plugin that keeps bulky tool output out of your context window, indexes it for search, and preserves session state across compaction.
Also: Coding Agent
-
by Google
Free, no-setup MCP server that grounds your coding agent in the Google Home API reference plus the Matter 1.5.1 and Thread 1.4.1 specifications.
Also: Coding Agent
-
by Snag
Snag's official remote MCP server — hands a coding agent the session replay, console logs, network trace and annotated screenshots captured for a bug, then takes the fix PR link back.
Also: Coding Agent
-
by AntV
Official AntV MCP server that turns a description of your data into a rendered chart — 26 visualization types from bar and line to sankey, mind-map, fishbone and geographic maps.
Also: Open Source
-
by Gentleman Programming
Persistent memory for coding agents as a single Go binary — SQLite and FTS5 behind MCP, an HTTP API, a CLI and a TUI, with no Node, Python or Docker required.
Also: Open Source
-
by Callstack
Give a coding agent a live feedback loop on real mobile, TV and desktop apps — inspect, tap, type and capture evidence on iOS, Android and HarmonyOS over MCP or a CLI.
Also: Open Source
-
by Hugging Face
Hugging Face's official remote MCP server — search and inspect models, datasets and Spaces, browse the Hub filesystem over hf:// URIs, and turn Gradio Spaces into callable tools.
Also: Open Source

by Payload
Payload's official MCP plugin — exposes every collection and global of a Payload CMS instance as MCP tools at /api/mcp, gated by Payload access control.
Also: Open Source
-
by Unleash
Unleash's official MCP server for feature flags — and unusually, it first judges whether a change needs a flag at all before creating one.
Also: Open Source
-
by Mantine
Mantine's official documentation server: gives an agent the component list, per-component docs and the exact props table, so generated React code matches the installed version.
Also: Open Source
