Running Individual MCP Servers Locally

Each MCP server reads from stdin / writes to stdout (JSON-RPC 2.0 framing). All daemons log to stderr — never stdout.

# trusty-search daemon (HTTP + MCP stdio)
RUST_LOG=info cargo run -p trusty-search -- start
# Query via CLI
cargo run -p trusty-search -- query "fn authenticate" --indexes <name>
# MCP stdio mode (used by Claude Code via .mcp.json)
cargo run -p trusty-search -- serve

# MPM daemon (there is no separate trusty-mpmd binary — the `tm`/`trusty-mpm`
# binary runs the same long-running daemon mode via the `daemon` subcommand)
RUST_LOG=info cargo run -p trusty-mpm --bin trusty-mpm -- daemon

# MPM CLI (tm / trusty-mpm) — the crate ships two identically-behaving bin
# targets, so `--bin` is required to disambiguate
cargo run -p trusty-mpm --bin trusty-mpm -- --help

# trusty-memory (MCP server + embedded Svelte UI)
RUST_LOG=info cargo run -p trusty-memory

# Report the daemon's listening port (stdout is clean — safe for shell substitution):
trusty-search port                                   # bare port: 7878
trusty-search port --addr                            # host:port: 127.0.0.1:7878
trusty-search port --json                            # {"addr":"127.0.0.1","port":7878}
# Shell substitution idiom — queries the daemon without guessing the port:
curl http://127.0.0.1:$(trusty-search port)/health

trusty-memory port                                   # bare port: 7070
trusty-memory port --addr                            # host:port: 127.0.0.1:7070
trusty-memory port --json                            # {"addr":"127.0.0.1","port":7070}
curl http://127.0.0.1:$(trusty-memory port)/health

# Fire-and-forget memory note from any agent (no MCP tool needed):
# Sub-agents spawned via Claude Code's Agent tool do not inherit MCP
# connections, so they cannot call `mcp__trusty-memory__memory_remember`
# directly. The `note` subcommand POSTs to the daemon's HTTP endpoint
# (`POST /api/v1/remember`) and returns immediately — the dispatch runs
# on a detached `tokio::spawn`. Failures degrade to stderr + zero exit.
trusty-memory note "key fact here" --palace my-project
trusty-memory note "another fact" --palace my-project --tag style --tag preferences

# Build a specific binary in release mode
cargo build --release -p trusty-search
./target/release/trusty-search start

To wire a locally-built binary into Claude Code, update your project's .mcp.json or ~/.claude/mcp.json to point command at the absolute path of the built binary (e.g. target/release/trusty-search).
