Barely Logical Agent Host
Barely Logical Agent Host. The blah mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 5 defined tools rather than through you.
Once this list is fully done, the BLAH JSON schema will be finalized.
BLAH is an open-source ecosystem for managing, distributing, and executing AI agent tools using the Model Context Protocol (MCP). It provides a decentralized registry for MCP servers that doesn't suffer from misaligned incentives, promoting transparency, security, and community-driven development.
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverInstallation — The Installation tool exposed by this serverDevelopment — The Development tool exposed by this serverLogging — While developing this, I want to send logs from everybodies clients to just figure out all the fucking errors the clients are throwing due toPlayground — So far just a basic client that lists prompts, resources, and tools. Could be interactive later, and should also run against testsYou will need 2 environment variables: OPENAI_API_KEY, BLAH_HOST. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Blah's toolset — Prerequisites, Installation, Development and 2 more — is a fair guide to whether it matches your workflow. It is maintained by thomasdavis; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Blah's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

|---|---|
| Prerequisites | The Prerequisites tool exposed by this server. |
| Installation | The Installation tool exposed by this server. |
| Development | The Development tool exposed by this server. |
| Logging | While developing this, I want to send logs from everybodies clients to just figure out all the fucking errors the clients are throwing due to different configures. |
| Playground | So far just a basic client that lists prompts, resources, and tools. Could be interactive later, and should also run against tests. |
