Mason

Unclaimed

by adrianczuczka

Mason builds context for LLMs — smart file sampling, concept maps, and change impact analysis. MCP server + CLI.

01 / Choose your client

02 / Before you connect

Authentication is not specified. Check the project instructions before connecting.

Install the runtime required by the project and make it available to your client.

Project instructionsEnvironment variable names (optional)

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: generated from public install instructions

claude mcp add --transport stdio 'mason' -- 'npx' '-y' '-p' 'mason-context' 'mason-mcp'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.

Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

18 of 18 tools

Documented tools (18)

From project documentation. A server handshake does not verify each tool’s description or behavior.

analyze_project

Git stats — hot files, stale dirs, commit conventions.

export_to_confluence

Sync the concept map to Confluence as PM-readable wiki pages.

full_analysis

One-shot orientation for unmapped projects: structure + samples + tests + git.

generate_snapshot_batch

Map step — returns one batch of files for the assistant to summarize.

get_code_samples

Smart file previews selected by architectural role.

get_context

First call for any task or bug. Matching features + files + tests + blast radius + freshness + recorded decisions, in one call.

get_impact

Call before editing a file. Traces what's affected — co-change history + references + related tests.

get_snapshot

First call for any architecture question. Loads the concept map — feature → file lookup — in one LLM-free call.

mason_check_drift

Feature-level staleness report — what changed since the snapshot, and whether to refresh incrementally or rebuild.

mason_complete_init

Marks the project as initialized once the playbook is done.

mason_init

Start here. Returns the Map-Reduce setup playbook. Idempotent.

mason_set_confluence

Configure Confluence credentials — two-step: list spaces, then persist.

reduce_snapshot

Reduce step — returns every partial + instructions to merge into a unified map.

save_decision

Record knowledge the code can't express — failed approaches, deprecations, conventions. Git-committed, PR-reviewed, drift-checked.

save_partial_snapshot

Persists the partial map for one batch.

save_snapshot

Persist the final unified map. Clears partials.

save_verification

Record verification verdicts — failures flag entries for re-mapping until fixed.

verify_snapshot

Spot-check map correctness — sampled entries + file skeletons for the assistant to judge, least-recently-verified first.

Tool change history

Compared across complete checks of the same configuration. Tools were listed, not invoked. Input-schema changes are not measured here.
